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.

This adds a new `GRIST_SANDBOX_FLAVOR=pyodide` option where the
version of Python used for the data engine is wasm, and so can
be run by node like the rest of the back end. It still runs as
a separate process.
There are a few small version changes made to packages to avoid
various awkwardnesses present in the current versions. All existing
tests pass.
This is very experimental. To use, you'll need something with
a bash shell and make. First do:
```
cd sandbox/pyodide
make setup # README.md and Makefile have details
cd ..
```
Then running Grist as:
```
GRIST_SANDBOX_FLAVOR=pyodide yarn start
```
should work. Adding a formula with content:
```
import sys; return sys.version
```
should return a different Python version than other sandboxes.
The motivation for this work is to have a form of sandboxing
that will work on Windows for Grist Electron (for Linux we have
gvisor/runsc, for Mac we have sandbox-exec, but I haven't found
anything comparable for Windows).
It also brings a back-end-free version of Grist a bit closer, for
use-cases where that would make sense - such as serving a report
(in the form of a Grist document) on a static site.
Summary:
Whole numbers, when imported from Excel into a Text column show up
without decimals (e.g. "300"), but when imported from Google Sheets show
up with decimals (e.g. "300.0"). The decimals are hard for end-users to
remove. Fix by treating whole numbers consistently as ints.
Test Plan: Added a fixture reproducing the issue, and a test case.

Summary:
This is just a convenience for myself. I happen to have a version of
gvisor on my Linux dev machine that differs from what we use in our
containers. There's a small difference in user setup that only manifests
itself when importing files. Grist uses a directory readable only by
the creating user, created outside the container, and then accessed
within the container. For that to work, the user identities have to
line up exactly. This adds a flag I can set in my environment to make
things work. An alternative solution that doesn't require a flag
would be to make the temporary directories readable by other users,
but that seemed a bigger change than justified.
Ideally we'd make a very robust and easy to run sandbox for Linux
users, and I have ideas there for the future.

Summary:
This diff adds a preview of the value of certain autocomplete suggestions, especially of the form `$foo.bar` or `user.email`. The main initial motivation was to show the difference between `$Ref` and `$Ref.DisplayCol`, but the feature is more general.
The client now sends the row ID of the row being edited (along with the table and column IDs which were already sent) to the server to fetch autocomplete suggestions. The returned suggestions are now tuples `(suggestion, example_value)` where `example_value` is a string or null. The example value is simply obtained by evaluating (in a controlled way) the suggestion in the context of the given record and the current user. The string representation is similar to the standard `repr` but dates and datetimes are formatted, and the whole thing is truncated for efficiency.
The example values are shown in the autocomplete popup separated from the actual suggestion by a number of spaces calculated to:
1. Clearly separate the suggestion from the values
2. Left-align the example values in most cases
3. Avoid having so much space such that connecting suggestions and values becomes visually difficult.
The tokenization of the row is then tweaked to show the example in light grey to deemphasise it.
Main discussion where the above was decided: https://grist.slack.com/archives/CDHABLZJT/p1661795588100009
The diff also includes various other small improvements and fixes:
- The autocomplete popup is much wider to make room for long suggestions, particularly lookups, as pointed out in https://phab.getgrist.com/D3580#inline-41007. The wide popup is the reason a fancy solution was needed to position the example values. I didn't see a way to dynamically resize the popup based on suggestions, and it didn't seem like a good idea to try.
- The `grist` and `python` labels previously shown on the right are removed. They were not helpful (https://grist.slack.com/archives/CDHABLZJT/p1659697086155179) and would get in the way of the example values.
- Fixed a bug in our custom tokenization that caused function arguments to be weirdly truncated in the middle: https://grist.slack.com/archives/CDHABLZJT/p1661956353699169?thread_ts=1661953258.342739&cid=CDHABLZJT and https://grist.slack.com/archives/C069RUP71/p1659696778991339
- Hide suggestions involving helper columns like `$gristHelper_Display` or `Table.lookupRecords(gristHelper_Display=` (https://grist.slack.com/archives/CDHABLZJT/p1661953258342739). The former has been around for a while and seems to be a mistake. The fix is simply to use `is_visible_column` instead of `is_user_column`. Since the latter is not used anywhere else, and using it in the first place seems like a mistake more than anything else, I've also removed the function to prevent similar mistakes in the future.
- Don't suggest private columns as lookup arguments: https://grist.slack.com/archives/CDHABLZJT/p1662133416652499?thread_ts=1661795588.100009&cid=CDHABLZJT
- Only fetch fresh suggestions specifically after typing `lookupRecords(` or `lookupOne(` rather than just `(`, as this would needlessly hide function suggestions which could still be useful to see the arguments. However this only makes a difference when there are still multiple matching suggestions, otherwise Ace hides them anyway.
Test Plan: Extended and updated several Python and browser tests.

Summary:
This diff adds a new `BulkAddOrUpdateRecord` user action which is what is sounds like:
- A bulk version of the existing `AddOrUpdateRecord` action.
- Much more efficient for operating on many records than applying many individual actions.
- Column values are specified as maps from `colId` to arrays of values as usual.
- Produces bulk versions of `AddRecord` and `UpdateRecord` actions instead of many individual actions.
Examples of users wanting to use something like `AddOrUpdateRecord` with large numbers of records:
- https://grist.slack.com/archives/C0234CPPXPA/p1651789710290879

- https://grist.slack.com/archives/C0234CPPXPA/p1663069291726159
I tested what made many `AddOrUpdateRecord` actions slow in the first place. It was almost entirely due to producing many individual `AddRecord` user actions. About half of that time was for processing the resulting `AddRecord` doc actions. Lookups and updates were not a problem. With these changes, the slowness is gone.
The Python user action implementation is more complex but there are no surprises. The JS API now groups `records` based on the keys of `require` and `fields` so that `BulkAddOrUpdateRecord` can be applied to each group.
Test Plan: Update and extend Python and DocApi tests.

Summary:
Fixes a bug noted here: https://grist.slack.com/archives/C069RUP71/p1662564341132349
This bug could happen quite easily as follows:
1. Have a formula in a summary table such as `$group.amount`. Typically there's also a `SUM` but that's not essential.
2. Find a group with nonzero values of `amount`.
3. Delete all rows in that group in the source table. Typically that just means one row in a lonely group.
4. The summary table row is automatically deleted.
5. Try to undo. This raises an error about trying to update a non-existent summary table row.
I tried to account for this undo problem in https://phab.getgrist.com/D3489 by not saving the updated value for `$group` when it was found to be empty. The reason this was insufficient is that `$group.amount` is immediately invalidated anyway when the source row(s) are deleted (I think because that's just how dependency relations involving references work) *and* the calculated value of `$group.amount` changes even if `$group` doesn't. For example, `$group.amount` may have previously been `[100, 200]`. After deleting the rows, `$group.amount` becomes `[0, 0]`. Keeping `$group` unchanged prevents `$group.amount` from just being `[]`, but deleting the source rows means that the amounts become the numeric default `0` which is still a change. This change in value is then noted which leads to saving an undo action to update the summary table record. All this happens in step 3 above, and the summary record is only deleted after that point.
This diff removes that special handling for `group` and instead adds a more general fix to `action_summary.py`. This inserts undo actions for deleted rows at the beginning of the undo list rather than at the end, which was already done for deleted tables and columns.

Python 2 only needs to be supported for the sake of old documents and formulas. This doesn't apply to the separate sandboxes that parse files for imports. Using Python 3 only allows using newer libraries and library versions. In particular, the latest version of openpyxl doesn't support Python 2. This will also make it easier to make other similar changes in the future, such as replacing messytables with a modern library. See https://grist.slack.com/archives/C0234CPPXPA/p1661261829343999?thread_ts=1661260442.837959&cid=C0234CPPXPA
