02ed4c59a0 (core) On welcome form pages, prevent accidental multiple submissions.
Summary:
Disable the submit button while a form submission is pending.

(We don't move to the next page without waiting since we get the page to
redirect to from the server.)

Test Plan: Tested manually by pausing the server and trying to submit multiple times.

0b1aa22ad9 (core) Ask the user some questions after they sign up and set their name.
Summary:
- Add a /welcome/info endpoint, to serve a page after /welcome/user
- Add a new forms module to factor out the styles that feel more natural for a web form.
- Simplify form submission using JSON with a BaseAPI helper.
- The POST submission to /welcome/info gets added to a Grist doc, using a
  specialPermit grant to gain access. A failure (e.g. missing doc) is logged
  but does not affect the user.

Test Plan: Added a test case.

bd6a54e901 (core) mitigate csrf by requiring custom header for unsafe methods
Summary:
For methods other than `GET`, `HEAD`, and `OPTIONS`, allow cookie-based authentication only if a certain custom header is present.

Specifically, we check that `X-Requested-With` is set to `XMLHttpRequest`. This is somewhat arbitrary, but allows us to use https://expressjs.com/en/api.html#req.xhr.

A request send from a browser that sets a custom header will prompt a preflight check, giving us a chance to check if the origin is trusted.

This diff deals with getting the header in place. There will be more work to do after this:
 * Make sure that all important endpoints are checking origin.  Skimming code, /api endpoint check origin, and some but not all others.
 * Add tests spot-testing origin checks.
 * Check on cases that authenticate differently.
    - Check the websocket endpoint - it can be connected to from an arbitrary site; there is per-doc access control but probably better to lock it down more.
    - There may be old endpoints that authenticate based on knowledge of a client id rather than cookies.

Test Plan: added a test

1654a2681f (core) move client code to core
Summary:
This moves all client code to core, and makes minimal fix-ups to
get grist and grist-core to compile correctly.  The client works
in core, but I'm leaving clean-up around the build and bundles to
follow-up.

Test Plan: existing tests pass; server-dev bundle looks sane
