Google is not approving new authorizations while it re-reviews our app, so
every path that starts a new Google connection now shows a PAUSED badge and a
"Notify me" button instead of Connect.
- Existing connections are untouched: sync, file picking and history still work.
- Notify me fires a connector_paused_clicked PostHog event and remembers the
choice in localStorage, so we can pull who to email when the review clears.
- One list in lib/connector-availability.ts drives every surface; removing the
two entries turns Google back on.
