test(e2e): scheduled messages and offline outbox; retry rate-limited scheduled-message calls
New end-to-end coverage for two Lotus features the October audit listed as
untested, checked against the server at each step:
- scheduled-messages.spec: schedule (tray + one delayed event on the
  server), Send now (arrives once, delayed event gone), cancel (gone from the
  server, never sent).
- offline-outbox.spec: offline, three messages show "Queued. Will send when
  you are back online"; back online, the server has each exactly once and in
  order; the queued marks clear.

The scheduled-messages test found a real bug: Synapse rate-limits delayed
event management per user, and a quick Send now then Cancel got a 429, so
the tray showed "Could not cancel this message" although nothing was wrong.
All scheduled-message calls (schedule, list, send now, cancel, restart) now
wait out a 429 (Retry-After, bounded) and retry; scheduling reuses its txnId.
Unit test for the retry helper.
