42060df29a (core) Formula autocomplete improvements for references and lookups
Summary:
Makes the following improvements to formula autocomplete:

- When a user types `$RefCol` (or part of it), also show `$RefCol.VisibleCol` (replace actual column names) in the autocomplete even before the `.` is typed, to help users understand the difference between a raw reference/record and its visible column.
- When a user types a table name, show `.lookupOne` and `.lookupRecords` in the autocomplete, again even before the `.` is typed.
- For `.lookupRecords(` and `.lookupOne(`, once the `(` is entered, suggest each column name as a keyword argument.
- Also suggest lookup arguments involving compatible reference columns, especially 'reverse reference' lookups like `refcol=$id` which are very common and difficult for users.
- To support these features, the Ace editor autocomplete needs some patching to fetch fresh autocomplete options after typing `.` or `(`. This also improves unrelated behaviour that wasn't great before when one column name is contained in another. See the first added browser test.

Summary:
The changes in this diff are sufficient to make this sequence work again:

```
./build electron-dev
bin/electron app/electron/runPrebuild.js
```

This brings up the local server within an electron window.

This is an unambitious diff, aimed at checking how rusty electron support had become. It does not revive Grist as a packaged electron app. The first substantial work needed would be to make the app aware of the local file system again, and think through how local files should be visualized and accessed now. In the past, there was a simple list of grist docs in a directory.

460f22b701 (core) Don't show hidden tables in table data options when adding widgets
Summary:
As reported in https://grist.slack.com/archives/C069RUP71/p1655316194602829, when a table is hidden by ACL, it was still showing as a blank 'ghost' option to select data when adding a widget:

{F55498}

The fix is simply to return `true` from `isHiddenTable` for empty table IDs, which indicate a table hidden by ACL. `TableRec.isHidden` is supposed to match this so I updated it too, and I cleaned up a tiny bit of other related code.

Test Plan: Extended `nbrowser/AccessRules1.ts` to test the data options when adding widgets.

dd8d2e18f5 (core) add an access token mechanism to help with attachments in custom widgets
Summary:
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.

4b258ae0fa (core) Fix 'select by' when adding summary table widget to page
Summary:
When adding a summary table widget to a page and using 'select by' in the add widget config (as opposed to in the right panel for an existing widget):

1. If an equivalent summary table already exists, use its referencing columns (if any) to construct link nodes. Previously the source table columns were being used instead, which could include referencing columns that don't have any equivalent in the summary table, and exclude referencing columns in the summary table.
2. If no such summary table exists yet, then keep using the source table columns, but only the selected groupby columns, and
3. After the summary table is created, correct the `linkTargetColRef` (which points to a source table column) to the corresponding column from the new summary table instead.

This fixes bugs which only appeared recently since 'select by' for a summary table previously involved no target columns.

Test Plan: Added two new tests to `nbrowser/SelectBySummaryRef`, and confirmed that they fail without the fixes to all three points above.

f91f45b26d (core) support granular read access for attachments
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.

51ff72c15e (core) Faster builds all around.
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.

  - Reduce imports of AWS dependencies (very noticeable speedup)
  - Avoid auto-loading global @types
  - Client code is now built with isolatedModules flag (for safe transpilation)
  - Use allowJs to avoid copying JS files manually.

  - Update eslint config, and include .eslintignore to avoid linting generated files.
  - Include a bunch of eslint-prompted and eslint-generated fixes

Dmitry S
a91d493ffc (core) Fix issue with 'UNEXPECTED ORDER OF CALLBACKS' in Client.ts.
Summary:
- Substantial refactoring of the logic when the server fails to send some
  messages to a client.
- Add seqId numbers to server messages to ensure reliable order.
- Add a needReload flag in clientConnect for a clear indication whent the
  browser client needs to reload the app.
- Reproduce some potential failure scenarios in a test case (some of which
  previously could have led to incorrectly ordered messages).
- Convert other Comm tests to typescript.
- Tweak logging of Comm and Client to be slightly more concise (in particular,
  avoid logging sessionId)

Note that despite the big refactoring, this only addresses a fairly rare
situation, with websocket failures while server is trying to send to the
client. It includes no improvements for failures while the client is sending to
the server.

(I looked for an existing library that would take care of these issues. A relevant article I found is https://docs.microsoft.com/en-us/azure/azure-web-pubsub/howto-develop-reliable-clients, but it doesn't include a library for both ends, and is still in review. Other libraries with similar purposes did not inspire enough confidence.)

Test Plan: New test cases, which reproduce some previously problematic scenarios.
