Summary:
When a user requests to read the contents of an attachment, only allow the request if there exists a cell in an attachment column that contains the attachment and which they have read access to.
This does not cover:
* Granular write access for attachments. In particular, a user who can write to any attachment column should be considered to have full read access to all attachment columns, currently.
* Access control of attachment metadata such as name and format.
The implementation uses a sql query that requires a scan, and some notes on how this could be optimized in future. The web client was updated to specify the cell to check for access, and performance seemed fine in casual testing on a doc with 1000s of attachments. I'm not sure how performance would hold up as the set of access rules grows as well.
Test Plan: added tests

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:
Call ActiveDoc.removeUnusedAttachments every hour using setInterval, and in ActiveDoc.shutdown (which also clears said interval).
Unrelated: small fix to my webhooks code which was creating a redis client on shutdown just to quit it.
Test Plan:
Tweaked DocApi test to remove expired attachments by force-reloading the doc, so that it removes them during shutdown. Extracted a new testing endpoint /verifyFiles to support this test (previously running that code only happened with `/removeUnused?verifyfiles=1`).
Tested the setInterval part manually.

Summary: Adds a migration in preparation for future work on tracking and deleting attachments. This includes a `_grist_Attachments.timeDeleted` column which isn't used yet, and changing the storage format of user columns of type `Attachments`. DocStorage now treats Attachments like RefList in general (since they use JSON), which also prompted a tiny bit of refactoring.

Summary:
Track 'data size' in ActiveDoc alongside row count. Measure it at most once every 5 minutes after each change as before, or after every change when it becomes high enough to matter.
A document is now considered to be approaching/exceeding 'the data limit' if either the data size or the row count is approaching/exceeding its own limit.
Unrelated: tweaked teamFreeFeatures.snapshotWindow based on Quip comments
Test Plan: Tested manually that data size is now logged after every change once it gets high enough, but only if the row limit isn't also too high. Still too early for automated tests.

Summary: As suggested by @dsagal in https://phab.getgrist.com/D3277#inline-36801, change to query `SUM(pgsize - unused)` instead of `SUM(pgsize)` to measure actual data size more accurately. Technically this doesn't reflect the database file size as accurately, but it should reflect sandbox memory usage better, and more importantly it should allow users to see data size decreasing when they delete stuff.
Test Plan: Tested manually by adding rows to a doc and looking at the logs. The data size is smaller and changes more granularly.

This makes it possible to set the type of a column to ReferenceList, but the UI is terrible
ReferenceList.ts is a mishmash of ChoiceList and Reference that sort of works but something about the CSS is clearly broken
ReferenceListEditor is just a text editor, you have to type in a JSON array of row IDs. Ignore the value that's present when you start editing. I can maybe try mashing together ReferenceEditor and ChoiceListEditor but it doesn't seem wise.
I think @georgegevoian should take over here. Reviewing the diff as it is to check for obvious issues is probably good but I don't think it's worth trying to land/merge anything.

This applies some mitigations suggested by SQLite authors when
opening untrusted SQLite databases, as we do when Grist docs
are uploaded by the user. See:
https://www.sqlite.org/security.html#untrusted_sqlite_database_files
Steps implemented in this diff are:
* Setting `trusted_schema` to off
* Running a SQLite-level integrity check on uploads
Other steps will require updates to our node-sqlite3 fork, since they
are not available via the node-sqlite3 api (one more reason to migrate
to better-sqlite3).
I haven't yet managed to create a file that triggers an integrity
check failure without also being detected as corruption by sqlite
at a more basic level, so that is a TODO for testing.

Summary:
Previously in {{D1053}} we switched to using BLOB as the "type" for all columns, to prevent SQLite from casting data unexpectedly. This diff now returns to more meaningful types. We apply marshalling to values when being placed in a column where a cast might occur, to inhibit such casting.
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.

Summary:
Loading all user data to run a migration is risky (creates more than usual
memory pressure), and almost never needed (only one migration requires it).
This diff attempts to run migrations using only metadata (_grist_* tables),
but retries if the sandbox tells it that all data is needed.
The intent is for new migrations to avoid needing all data.

Summary:
- Introduce a new SQLiteDB migration, which adds DB columns for formula columns
- Newly added columns have the special ['P'] (pending) value in them
(in order to show the usual "Loading..." on the first load that triggers the migration)
- Calculated values are added to .stored/.undo fields of user actions.
- Various changes made in the sandbox to include .stored/.undo in the right order.
- OnDemand tables ignore stored formula columns, replacing them with special SQL as before
- In particular, converting to OnDemand table leaves stale values in those
columns, we should maybe clean those out.
Some tweaks on the side:
- Allow overriding chai assertion truncateThreshold with CHAI_TRUNCATE_THRESHOLD
- Rebuild python automatically in watch mode
Test Plan: Fixed various tests, updated some fixtures. Many python tests that check actions needed adjustments because actions moved from .stored to .undo. Some checks added to catch situations previously only caught in browser tests.

Deliberate changes:
* save snapshots to s3 prior to migrations.
* label migration snapshots in s3 metadata.
* avoid pruning migration snapshots for a month.
Opportunistic changes:
* Associate document timezone with snapshots, so pruning can respect timezones.
* Associate actionHash/Num with snapshots.
* Record time of last change in snapshots (rather than just s3 upload time, which could be a while later).
This ended up being a biggish change, because there was nowhere ideal to put tags (list of possibilities in diff).
