Summary:
The problem is that the implementation for a summary update was relying on type consistency to get columns (ie: matches agains colId and type).
Type consistency is an attempt at maintaining consistent type across same-named column for summaries of same table.
But the problem is that the consistency of types is NOT a strict guarantee or an invariant, more of a best-effort attempt (there are too many possible sequences of operations possible with renaming/adding/removing in summary tables and the underlying table).
With current implementation and with a document violating the type consistency, a summary table could end up with fields referencing columns to the former summary table (more detail below(1)). Which is a bad state (yields js errors on the client).
This diff fixes this issue by relaxing the type comparison when search for same-named column.
(1) __Below is a description of how a violation of type consistency could end-up in bad state document (example taken from the reported bug):__
> In this document, let's assume two summary tables `Table1 [by A]` and `Table1 [Totals]`. Let's also assume Table1 and `Table1 [Totals]` both have an `Amount(Numeric)` column, and that `Table1 [by A]` has one `Amount(Any)` column (violating the type consistency principle). Now when users wanted to change the `Table1 [Totals]` section to group by 'A', grist found that there is already a summary table with same grouping. But it couldn't find a matching column for `Amount(Numeric)` so it created a new one. Except that because there was still an `Amount(Any)` the new column was named `Amount2` which caused following code to ignore it and in particular forgetting to update it's corresponding section's field which was then pointing toward the column of a different table (which is bad).
Test Plan: Added python test.

Summary:
Undo often leads to errors, especially with summary tables. One example is here: https://grist.slack.com/archives/C069RUP71/p1662564341132349
This diff simply decorates all relevant tests in 3 files testing summary tables with `@test_engine.test_undo`. This didn't catch any new bugs or reveal the problem in the thread above, but it seems good to have.

Summary:
Changes auto-generated summary table IDs from e.g. `GristSummary_6_Table1` to `Table1_summary_A_B` (meaning `Table1` grouped by `A` and `B`). This makes it easier to write formulas involving summary tables, make API requests, understand logs, etc.
Because these don't encode the source table ID as reliably as before, `decode_summary_table_name` now uses the summary table schema info, not just the summary table ID. Specifically, it looks at the type of the `group` column, which is `RefList:<source table id>`.
Renaming a source table renames the summary table as before, and now renaming a groupby column renames the summary table as well.
Conflicting table names are resolved in the usual way by adding a number at the end, e.g. `Table1_summary_A_B2`. These summary tables are not automatically renamed when the disambiguation is no longer needed.
A new migration renames all summary tables to the new scheme, and updates formulas using summary tables with a simple regex.
Test Plan:
Updated many tests to use the new style of name.
Added new Python tests to for resolving conflicts when renaming source tables and groupby columns.
Added a test for the migration, including renames in formulas.

Summary: When the `getSummarySourceGroup` function (used by the `$group` column) finds that the group is empty, raise a new special exception `EmptySummaryRow`. The engine catches this exception, avoids saving a value to the cell, and removes the record.

Summary:
Updating one summary groupby columns is handle by the
`update_summary_section`. That routine is in charge of creating a new
summary table and transfer all possible columns from old table to the
new one, so that the new table appear to change only the minimum to
users.
The problem that this diff address is that, the logic to decide what columns we need to keep, only applies to the visible
fields and ignore the hidden columns, causing all hidden columns to be removed. This diff, simply
changes that routine to address all columns.
the mutliple fixes on the test_summary2.py result from a change of
ordering of columns: the culprit is the `group` columns, which is by
default a hidden columns and that had to be explicitely added back to
the new summary table. It is now transferred automatically, like other
columns, which does cause a little change of ordering on the db. This
should not result in any display order changes for the users.

- users removing a group by column that is of type numeric was
resulting in the column missing from the summary table. Where
instead is should be present as a 'SUM($group.${col.colId})'
formula column
- this diff fixes that issue and adds unit test
Test Plan: Should not break anything. Adds not test case.

Summary: This is the first step towards raw data views, merely adding metadata without any UI. Every 'normal' table now has a widget referenced by `rawViewSectionRef`. It has no parent view/page and cannot actually be viewed for now. The widget is created during the AddTable user action, and the migration creates a widget for existing tables.
Test Plan: Many tests had to be updated, especially tests that listed all view sections and/or fields.

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.
