pewdiepie-archdaemon e0e250d023 Calendar: cross-session delete sync — 404 = success, refetch on tab focus ...

A stale event deleted on one device stayed undeletable on every other
session: the cached row showed up, the DELETE call returned 404 (server
already removed it), the optimistic catch-block restored the row, and
the user could never clear it.

- Treat HTTP 404 on DELETE as success — the event is already gone,
  which is the state we wanted. Skip the optimistic restore.
- Re-fetch the visible range on document `visibilitychange` (mobile
  app returns to foreground) and on window `focus` (desktop alt-tab),
  throttled to once per 10s so rapid tab-flipping doesn't hammer the
  API. Without a focus refresh, mobile only got fresh server state at
  page-load and lived on stale data until a full reload.
