Serve the script as /app.js, cached until a deploy changes it

Browse Source 
The page loaded its script inline. It now names /app.js?v=<hash> (login.js for
the sign-in page), the hash of the script's contents: the script is served
immutable for a year and the page no-cache, so a browser fetches the script
again only when a deploy changes it and so its name.

Also fixes a race in the mark-everything-read test: it waited on a badge that
was seldom 0 to begin with, so a mark-unread still in flight could land after
the read-all.

The page is markup and CSS in `web/index.html` and TypeScript in `web/src/`. `build.rs` runs
`web/build.mjs`, which uses swc to strip the types, put the script into the page and minify the
whole thing, and the result is `include_str!`d into the binary. So **every page change needs a
`web/build.mjs`, which uses swc to strip the types and minify the script into `app.js` (and

loads its script as `/app.js?v=<hash of its contents>`: the page is served `no-cache` and the

rebuild** before it is visible, and building needs node and `npm ci` run once.
The files in `web/src` are not modules. They are one script split up, concatenated in the order
