Summary:
This improves support for access control on document modifications. It adds:
* Checking of create/remove/update access for row-level changes.
* Use of `newRec` variable in formulas.
It is now possible to have distinct clients with read+write access to different rows of the same table.
This is another incremental step. There are deficiencies in actions that include schema changes, and many other lacunae. But the overall flow is taking shape.
Access control is done at the DocAction level, requiring the sandbox to process the UserActions, and then be reverted if the action proves unlawful. This could be optimized away in many simple and important cases, but I'm not sure it is possible to avoid in general.

Summary:
when a document is opened, and Calculate results in
a change, that change is not attributed to 'grist' rather than
to the user's email.
Some minor tweaks included to freshen some related dev scripts.

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.

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.

Summary: This makes the user's role (owner/editor/viewer) available in ActiveDoc methods. No use of that information is made yet, other than to log it. The bulk of the diff is getting a handle on the various ways the methods can be called, and systematizing it a bit more. In passing, access control is added to broadcasts of document changes, so users who no longer have access to a document do not receive changes if they still have the document open.
Test Plan: existing tests pass; test for broadcast access control added

Summary: This moves enough server material into core to run a home server. The data engine is not yet incorporated (though in manual testing it works when ported).
