* fix(sync): never toast third-party cloud-sync errors; log to console only
The reader's per-book auto-sync surfaced an "Cloud sync authentication failed.
Reconnect in Settings." toast on any AUTH_FAILED (e.g. an expired web Google
Drive token), interrupting reading. Background sync failures shouldn't pop a
toast — drop it and console.warn every sync error instead (the AUTH_FAILED
branch only chose toast-vs-console, so it collapses to a plain log). Removes the
now-unused authFailedToast + useTranslation/FileSyncError imports.
Manual "Sync now" (FileSyncForm) still reports its result — it's a deliberate,
foreground action. Native cloud sync (useBooksSync) is unaffected.

* feat(sync): surface an expired cloud-sync session in the reader + Settings
With sync-error toasts silenced, an expired third-party session (e.g. the
short-lived web Google Drive token) had no UI indicator. Surface it without the
old per-failure error toast:
- Reader: a single top-right `hint` ("Google Drive session expired. Reconnect in
Settings.") — the same affordance as the native "Reading Progress Synced"
hint. De-duplicated via a per-instance ref so it shows once, not on every
page-turn sync; reset on a successful sync / provider switch (web reconnect
reloads anyway).
- Settings → Google Drive: Disconnect swaps to Reconnect when the session is
expired, and "Sync now" is disabled (FileSyncForm gains a `syncNowDisabled`
prop) so a sync that would just fail isn't offered. No hint text in Settings.
- webTokenStore.hasValidWebDriveToken() backs the web detection (the token lives
in sessionStorage; native auto-refreshes so it doesn't apply there).
