Summary:
Allow requests from untrusted origins instead of returning an error, but don't allow credentials (Cookie header) or API keys (Authorization header).
Allow setting the header `Content-type: application/json` as an alternative to `X-Requested-With: XMLHttpRequest` to make it easier for clients to make POST/PUT/PATCH/DELETE requests without authentication.

With this, a custom widget can render an attachment by doing:
```
const tokenInfo = await grist.docApi.getAccessToken({readOnly: true});
const img = document.getElementById('the_image');
const id = record.C[0]; // get an id of an attachment
const src = `${tokenInfo.baseUrl}/attachments/${id}/download?auth=${tokenInfo.token}`;
img.setAttribute('src', src)
```
The access token expires after a few mins, so if a user right-clicks on an image
to save it, they may get access denied unless they refresh the page. A little awkward,
but s3 pre-authorized links behave similarly and it generally isn't a deal-breaker.

Summary:
Building:
- Builds no longer wait for tsc for either client, server, or test targets. All use esbuild which is very fast.
- Build still runs tsc, but only to report errors. This may be turned off with `SKIP_TSC=1` env var.
- Grist-core continues to build using tsc.
- Esbuild requires ES6 module semantics. Typescript's esModuleInterop is turned
on, so that tsc accepts and enforces correct usage.
- Client-side code is watched and bundled by webpack as before (using esbuild-loader)
Code changes:
- Imports must now follow ES6 semantics: `import * as X from ...` produces a
module object; to import functions or class instances, use `import X from ...`.
- Everything is now built with isolatedModules flag. Some exports were updated for it.
Packages:
- Upgraded browserify dependency, and related packages (used for the distribution-building step).
- Building the distribution now uses esbuild's minification. babel-minify is no longer used.
Test Plan: Should have no behavior changes, existing tests should pass, and docker image should build too.

Summary:
For self-hosted Grist, forward auth has proven useful, where
some proxy wrapped around Grist manages authentication, and
passes on user information to Grist in a trusted header.
The current implementation is adequate when Grist is the
only place where the user logs in or out, but is confusing
otherwise (see https://github.com/gristlabs/grist-core/issues/207).
Here we take some steps to broaden the scenarios Grist's
forward auth support can be used with:
* When a trusted header is present and is blank, treat
that as the user not being logged in, and don't look
any further for identity information. Specifically,
don't look in Grist's session information.
* Add a `GRIST_IGNORE_SESSION` flag to entirely prevent
Grist from picking up identity information from a cookie,
in order to avoid confusion between multiple login methods.
* Add tests for common scenarios.

Summary:
This makes a `user.SessionID` value available in information about the user, for use with trigger formulas and granular access rules. The ID should be constant within a browser session for anonymous user. For logged in users it simply reflects their user id.
This ID makes it possible to write access rules and trigger formulas that allow different anonymous users to create, view, and edit their own records in a document.
For example, you could have a brain-storming document for puns, and allow anyone to add to it (without logging in), letting people edit their own records, but not showing the records to others until they are approved by a moderator. Without something like this, we could only let anonymous people add one field of a record, and not have a secure way to let them edit that field or others in the same record.
Also adds a `user.IsLoggedIn` flag in passing.
Test Plan: Added a test, updated tests. The test added is a mini-moderation doc, don't use it for real because it allows users to edit their entries after a moderator has approved them.

Summary:
* Remove adjustSession hack, interfering with loading docs under saml.
* Allow the anonymous user to receive an empty list of workspaces for
the merged org.
* Behave better on first page load when org is in path - this used to
fail because of lack of cookie. This is very visible in grist-core,
as a failure to load localhost:8484 on first visit.
* Mark cookie explicitly as SameSite=Lax to remove a warning in firefox.
* Make errorPages available in grist-core.
This changes the default behavior of grist-core to now start off in
anonymous mode, with an explicit sign-in step available. If SAML is not configured,
the sign-in operation will unconditionally sign the user in as a default
user, without any password check or other security. The user email is
taken from GRIST_DEFAULT_EMAIL if set. This is a significant change, but
makes anonymous mode available in grist-core (which is convenient
for testing) and makes behavior with and without SAML much more consistent.

Summary:
This changes how user attributes are loaded. They are now loaded
directly from sqlite, with per-session caching. Optimizations
considered but not addressed yet are (1) adding indexes to user attribute
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
the same document via different clients with occasional document
reloads.
Code for updating when schema or rule changes happen is moved
around but not improved in any meaningful way in 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.

a publically shared doc within that org.
* Likewise, for the anonymous user (but for a different reason).
This diff tweaks the web client to permit accessing a doc when
org information is unavailable.
It also changes how redirects happen for the anonymous user when
