Linus Rath 687e7cc012 feat: move offline mode onto the encrypted local store
The IndexedDB cache, its crypto, the responder and the page-side sync
go. lib/offline keeps its structure, policy, wipes, sign-out gates and
notices; answers, the outbox and sync now live in lib/store, in a worker
behind lib/store/client/api.ts.

What users get besides that:
- every folder is kept, not just the Inbox and opened ones
- delete for good and empty trash work offline
- a change the server refuses, or that meets a message changed on
  another device, is shown instead of dropped
- a send whose response got lost is looked up by a Message-ID fixed when
  it was queued, then finished, submitted or sent again
- with the store on, a start paints from the local copy, then connects

An account the app drops by itself no longer wipes its data: only a
sign-out or an explicit removal does. The outbox of the old database
moves over once, in lib/offline/migrate-legacy.ts, and the old database
goes only after the store committed. `isNetworkFailure` now counts
timeouts and proxy 5xx. Sends and outbox requests are never answered
from the device.

Tests moved with the code: cache.test.ts and responder.test.ts are
replaced by lib/store/__tests__/, and review-fixes.test.ts, outbox.test.ts
and client-fallback.test.ts now run the real engine on node:sqlite.
Changed assertions: an uncertain send is looked up rather than left alone
forever, destroy and empty trash are queued rather than refused, and #9
(opened folders) became "a folder the server deleted goes", since all
folders are kept.

/**
* The server refused this account's refresh token for good. Nothing wipes on
* this yet: a refused account is dropped, and its local data stays for the next
* sign-in. HOOK: the wipe work (lib/store/wipe) registers here to act on a
* permanent rejection. Free of the stores, so the auth store can call it.
