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.

This is a follow up diff for https://phab.getgrist.com/D3021. Y-axis
draggable list used to blink when user changed either one of the x
axis or groupdata column.
This was due to the fact that all of theses axis are stored into the
same array and changing one of them changes the whole array even
though items relative to the y-axis actually were not changing.
This diff addresses this issue by 1) being carefull at not updating
the array of items when the changes do not impact y axis. And 2) by
adding a freeze observable allowing to freeze the draggable list of
y-axis while actions are being treated on the server.

Summary:
Allows selecting by a reflist in another table. This generalises cursor-linking with a ref column, but now it's filter linking.
Added another case to LinkingState where the source column is a reflist to the target table, filtering by the id column.
Updated convertQueryFromRefs and related functions to handle this since the id column has no column ref. In this case the string 'id' is used instead of a number.
LinkingState also checks if the source value is a reflist and uses that as the list of filter values instead of a single-element list of the cell value.
Indirect linking also works, where the source and target columns both are both references to the same table. This was the plan for a source reflist and target ref column.
I was surprised to see it also works perfectly when both columns are reflists, and it filters rows where there's an intersection!
Adding rows to the target section using the selected source record for default values is iffy. When filtering by row ID, there's no column for defaults, so the new row disappears.
For a source reflist and target ref, the first value of the reflist is the default, which is okayish. When both are reflists, the full source reflist is the default for the target column.
This seems like a bit much but just using the first value seems a bit arbitrary when there's room for all of them?
While doing all this I noticed an unrelated bug which I fixed as I was refactoring. Previously cursor linking based on a reference column did not update the cursor in the link target
when the value of the selected reference cell changed. Now cursor linking uses a floating row model like most other cases to observe the value correctly.

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
