Builds upon https://phab.getgrist.com/D3328
- Add HomeDB column `Document.gracePeriodStart`
- When the row count moves above the limit, set it to the current date. When it moves below, set it to null.
- Add DataLimitStatus type indicating if the document is approaching the limit, is in a grace period, or is in delete only mode if the grace period started at least 14 days ago. Compute it in ActiveDoc and send it to client when opening.
- Only allow certain user actions when in delete-only mode.
Follow-up tasks related to this diff:
- When DataLimitStatus in the client is non-empty, show a banner to the appropriate users.
- Only send DataLimitStatus to users with the appropriate access. There's no risk landing this now since real users will only see null until free team sites are released.
- Update DataLimitStatus immediately in the client when it changes, e.g. when user actions are applied or the product is changed. Right now it's only sent when the document loads.
- Update row limit, grace period start, and data limit status in ActiveDoc when the product changes, i.e. the user upgrades/downgrades.
- Account for data size when computing data limit status, not just row counts.

- Future diffs should make this page prettier and easily accessible
- Shows a list of user tables
- Clicking on a table name shows its `rawViewSection` by setting `GristDoc.viewModel.activeSectionId`. Note that in this case `GristDoc.viewModel` is an empty record, so this is a bit of a hack, but it works well and causes no known issues.

- 'Delete widget' is disabled in the 3-dot widget menu.
- Prevent hiding columns:
- "Hide column" in the column context menu is disabled
- The "VISIBLE/HIDDEN COLUMNS" section of the right panel > Table > Widget is hidden

However we didn't prevent the user from doing it and it could cause unexpected behaviour such as a missing chart.
This diff addresses that issue by doing two following thing:
1) it prevents user from adding non numeric column as series and
2) it makes sure that if there is a non numeric series it does not mess up the chart (it still can happen that a non numeric series ends up in charts even with 1) for instance if users convert a series' column to a non numeric column for instance).

Summary:
With this diff, when a user opens a Grist document in a browser, they will be able to view its contents without waiting for the data engine to start up. Once the data engine starts, it will run a calculation and send any updates made. Changes to the document will be blocked until the engine is started and the initial calculation is complete.
The increase in responsiveness is useful in its own right, and also reduces the impact of an extra startup time in a candidate next-generation sandbox.
A small unrelated fix is included for `core/package.json`, to catch up with a recent change to `package.json`.
A small `./build schema` convenience is added to just rebuild the typescript schema file.

Summary:
This removes the need for any information drawn from the content of recent actions when loading a document.
The undo/redo system does need some facts about recent actions up front. But that system has an important restriction: only actions a particular client is known to have generated can be undone by that client.
So in this diff, as we store which client has performed an action, we also store the few pieces of metadata about that action that the undo/redo system needs: `linkId`, `otherId`, `rowIdHint`, `isUndo` fields. These are all small integers (or in one case a boolean).
An existing limitation is that information about which client has performed which action is stored in memory in the worker, and not persisted anywhere. This diff does not change that limitation, meaning that undos continue to not survive a worker transition. A reasonable way to deal with that would be to back the store with redis.

replace the destination table values, unless the incoming
values are blank.
Additional merge strategies are implemented in the data
engine, but the import dialog only uses one of the
strategies currently. The others can be exposed in the UI
in the future, and tweak the behavior of how source
and destination values should be merged in different contexts,
such as when blank values exist.

This diff brings in the new welcome tour. It builds upon `client/ui/OnBoardingPopup` that was committed to that purposes. Per this diff, the tour is accessible behind a flag and won't be visible to user: few caveats listed below needs to be adressed first.
This diff also brings few changes to onboarding module.
- allow to refer to element with selector
- usually dynamic selection of element sounds useful for when the
element does not exist yet when the tour starts. But the actual
reason when add it here, is to allow selecting the first cell.
- if the selector yields undefined (missing element), the popup
is simply skipped
- got rid of the internal registry to link between popup contents
and popup options. All is now define in the same interface. Registry
overall felt overkill and not needed.
- adds an option to show message as a simple modal that is centered
on the screen
This diff also brings the new welcome tour and hide it behind a flag
CAVEATS that need to be addressed in follow up commit:
- The url needs cleanup, #repeat-welcome-tour sticks to it and so even when navigating to home page. This could eventually become an issue: if user opens another document it would starts the onboarding tour again.
- For now you have to manually make sure the right panel is opened with the Column tab selected before starting the tour.
- On boarding tours were not designed with mobile support in mind. So probably a good idea to disable.
- Backend support needs to be done (persistence of first time user).
Test Plan:
Updated `projects/OnBoardingPopup` and adds new `nbrowser/welcomeTour`
To launch the tour:
- open any document
- open manually the right panel and the field tab
- append the flag `#repeat-welcome-tour` at the end of the url in the url bar and reload the page

stray columns were not visible to this check, and instead caused later table
additions to fail.
This diff fixes the check to fail the action that causes stray columns, and
to restore the doc to a consistent state.
Note that this only handles schema-metadata inconsistencies, but an undo of a
non-last action can easily create other surprises.
