The page client no longer resolves accountId from /v1/users/me. accountId is only sent when passed with --account-id, and a 403 for it now raises a clear error telling the user to omit it because the server scopes the listing to the caller's own account.
Adds point_alarm.py (flattening, secret masking, SQLite upsert store, paged fetch with 403 fallback, CSV/TXT export, shared filter loader), nowcast-point-page.py CLI and unit tests. Register will read the shared filter from nowcast-point-alarm-filter.json instead of repeating it in the CSV.
