This is a somewhat experimental change, that will implement permitted parts of an undo if not all parts are permitted. This is in preparation for trigger columns, where it may become common for a change in a record resulting in a change to an automatic change to another that the user cannot edit directly. How to undo such an action is somewhat unclear. One option is to undo the permitted parts, and then the triggers can rerun.
The general case is a bit of a can of worms, and feels adjacent to merging/rebasing etc.
Oh: it would probably be important in general to communicate to the user that an undo was partial, but this diff doesn't do that. It would need some new plumbing.

The `_repairWorkspaceGuests` method is slow for workspaces with large numbers of documents. It makes a query that produces a lot of rows. The query itself is tolerable, but TypeORM processing uses enough CPU to be a likely culprit in some production instability. This diff splits the query into two pieces that are logically independent, but which when combined were resulting in the number of rows being the product of the two pieces. Once split, there is also a where clause that can be applied to one of the pieces.
The purpose of the method is to add every user that a document within a workspace is shared with to a "guest" group of the workspace itself. The design of "guest" groups is not ideal, but this diff leaves the design unchanged and is intended only to speed up operation.
Made some small tweaks to the timing of a flakey test, and temporarily recreated the `samples` directory removed in a previous diff (this is currently breaking tests badly on a fresh worker without a `samples` directory lying around)

The `engine.apply_user_actions` method now returns a `direct` array, with a boolean for each `stored` action, set to `true` if the action is attributed to the user or `false` if it is attributed to the engine. `GranularAccess` ignores actions attributed to the engine when checking for edit rights.

The benefit is that Grist documents become easier to interact with via regular database clients/libraries, which often rely on the column type more than a purely SQLite tool would.
On column type conversion, we run all blobs in the column through a decode/encode cycle so if they no longer need to be marshalled they revert to native type. This could be optimized further, it is somewhat brute force.

* Adds a `UUID()` python function, since using python's uuid.uuidv4 hits a problem accessing /dev/urandom in the sandbox. UUID makes no particular quality claims since it doesn't use an audited implementation. A difficult to guess code is convenient for some use cases that `SELF_HYPERLINK()` enables.
The canonical URL for a document is mutable, but older versions generally forward. So for implementation simplicity the document url is passed it on sandbox creation and remains fixed throughout the lifetime of the sandbox. This could and should be improved in future.
The URL is passed into the sandbox as a `DOC_URL` environment variable.
The code for creating the URL is factored out of `Notifier.ts`. Since the url is a function of the organization as well as the document, some rejiggering is needed to make that information available to DocManager.
On document imports, the new document is registered in the database slightly earlier now, in order to keep the procedure for constructing the URL in different starting conditions more homogeneous.

tables and (2) swapping in a thinner sqlite wrapper.
The main benefit of this diff is that changes to user attribute
tables now work. Clients whose user attributes are not changed
see no effect; clients whose user attributes have changed have
their document reloaded.
For the purposes of testing, the diff includes a tweak to
GristWSConnection to be "sticky" to a specific user when reloading
(and support machinery on the server side to honor that). Until
now, if a GristWSConnection reloads, it uses whatever the current
default user is in the cookie-based session, which can change.
This was complicating a test where multiple users were accessing

reloads.

- Columns that rely on float values should derive from NumericColumn, so
that set() ensures that a float is stored even if loading an int.
- Parse unmarshallable values (['U']) into an object that can be encoded

Summary:
This implements row-level access control for outgoing messages, replacing the document reloading placeholder that was there before.
* Prior to broadcasting messages, GranularAccess is notified of actions+undo.
* While broadcasting messages to different sessions, if we find we need row level access control information, rows before and after the change are reconstructed.
* Messages are rewritten if rows that were previously forbidden are now allowed, and vice versa.
The diff is somewhat under-tested and under-optimized. Next step would be to implement row-level access control for incoming actions, which may result in some rejiggering of the code from this diff to avoid duplication of effort under some conditions.

Loading all user data to run a migration is risky (creates more than usual

With recent changes to action history, we can now remove the temporary
`finalRowContent` field from change details, since all the information
we need is now in the ActionSummary.
We also now have more information about the state of the common ancestor,
which previously we could not get either from ActionSummary or from
`finalRowContent`. We take advantage of that to flesh out rendering
differences where there are some changes locally and some changes
remotely.
There's still a lot more to do, this is just one step.

Summary:
Type conversions and formula tranforms wait for the user and bundle multiple
actions. When an unrelated action is done (e.g. adding a page widget or a
column), we want to finalize the transform before applying it.
The approach turns out fairly complicated. There is an implicit queue of
bundles (which we don't let grow beyond 2, as that's too abnormal). Bundles may
be finalized by a user clicking something, or by an unrelated action/bundle, or
(as before) by transform DOM getting disposed.
- Updated RecordLayout to use bundleActions() helper
- Added support for nesting bundleActions inside another bundle (needed for
setting visibleCol during type change)
- In an unrelated tweak, when in debug-log in ActiveDoc, use a short representation of result.

Summary:
This fixes a two problems:
* A mistake in `KeyedMutex.runExclusive`.
* Logic about saving a document to s3 when the document is found to match what is already there.
`HostedStorageManager.flushDoc` could get caught in a loop if a document was uploaded to s3 and then, without any change to it, marked as dirty. Low level code would detect there was no change and skip the upload; but then the snapshotId could be unknown, causing an error and retries. This diff fixes that problem by discovering the snapshotId on downloads and tracking it. It also corrects a mutex problem that may have been creating the scenario. A small delay is added to `flushDoc` to mitigate the effect of similar problems in future. Exponential backoff would be good, but `flushDoc` is called in some situations where long delays would negatively impact worker shutdown or user work.

Summary:
In an emergency, we may want to serve certain documents with "old" workers as we fix problems. This diff adds some support for that.
* Creates duplicate task definitions and services for staging and production doc workers (called grist-docs-staging2 and grist-docs-prod2), pulling from distinct docker tags (staging2 and prod2). The services are set to have zero workers until we need them.
* These new workers are started with a new env variable `GRIST_WORKER_GROUP` set to `secondary`.
* The `GRIST_WORKER_GROUP` variable, if set, makes the worker available to documents in the named group, and only that group.
* An unauthenticated `/assign` endpoint is added to documents which, when POSTed to, checks that the doc is served by a worker in the desired group for that doc (as set manually in redis), and if not frees the doc up for reassignment. This makes it possible to move individual docs between workers without redeployments.
The bash scripts added are a record of how the task definitions + services were created. The services could just have been copied manually, but the task definitions will need to be updated whenever the definitions for the main doc workers are updated, so it is worth scripting that.
For example, if a certain document were to fail on a new deployment of Grist, but rolling back the full deployment wasn't practical:
* Set prod2 tag in docker to desired codebase for that document
* Set desired_count for grist-docs-prod2 service to non-zero
* Set doc-<docid>-group for that doc in redis to secondary
* Hit /api/docs/<docid>/assign to move the doc to grist-docs-prod2
(If the document needs to be reverted to a previous snapshot, that currently would need doing manually - could be made simpler, but not in scope of this diff).

Summary:
This is a prototype for expanding the conditions that can be used in granular ACLs.
When processing ACLs, the following variables (called "characteristics") are now available in conditions:
* UserID
* Email
* Name
* Access (owners, editors, viewers)
The set of variables can be expanded by adding a "characteristic" clause. This is a clause which specifies:
* A tableId
* The name of an existing characteristic
* A colId
The effect of the clause is to expand the available characteristics with all the columns in the table, with values taken from the record where there is a match between the specified characteristic and the specified column.
Existing clauses are generalized somewhat to demonstrate and test the use these variables. That isn't the main point of this diff though, and I propose to leave generalizing+systematizing those clauses for a future diff.
Issues I'm not dealing with here:
* How clauses combine. (The scope on GranularAccessRowClause is a hack to save me worrying about that yet).
* The full set of matching methods we'll allow.
* Refreshing row access in clients when the tables mentioned in characteristic tables change.
* Full CRUD permission control.
* Default rules (part of combination).
* Reporting errors in access rules.
That said, with this diff it is possible to e.g. assign a City to editors by their email address or name, and have only rows for those Cities be visible in their client. Ability to modify those rows, and remain updates about them, remains under incomplete control.

Summary:
For methods other than `GET`, `HEAD`, and `OPTIONS`, allow cookie-based authentication only if a certain custom header is present.
Specifically, we check that `X-Requested-With` is set to `XMLHttpRequest`. This is somewhat arbitrary, but allows us to use https://expressjs.com/en/api.html#req.xhr.
A request send from a browser that sets a custom header will prompt a preflight check, giving us a chance to check if the origin is trusted.
This diff deals with getting the header in place. There will be more work to do after this:
* Make sure that all important endpoints are checking origin. Skimming code, /api endpoint check origin, and some but not all others.
* Add tests spot-testing origin checks.
* Check on cases that authenticate differently.
- Check the websocket endpoint - it can be connected to from an arbitrary site; there is per-doc access control but probably better to lock it down more.
- There may be old endpoints that authenticate based on knowledge of a client id rather than cookies.

This makes it possible to serve a table or tables only to owners.
* The _grist_ACLResources table is abused (temporarily) such that rows of the form `{colId: '~o', tableId}` are interpreted as meaning that `tableId` is private to owners.
* Many websocket and api endpoints are updated to preserve the privacy of these tables.
* In a document where some tables are private, a lot of capabilities are turned off for non-owners to avoid leaking info indirectly.
* The client is tweaked minimally, to show '-' where a page with some private material would otherwise go.
No attempt is made to protect data from private tables pulled into non-private tables via formulas.
There are some known leaks remaining:
* Changes to the schema of private tables are still broadcast to all clients (fixable).
* Non-owner may be able to access snapshots or make forks or use other corners of API (fixable).
* Changing name of table makes it public, since tableId in ACLResource is not updated (fixable).
Security will require some work, the attack surface is large.
