The first Gmail backfill leaves the account at "pending · never synced" until it
fully completes (the sync_runs row only finalizes at the end), so there was no
feedback. /api/email/status now also returns captured_emails (total, which climbs
page-by-page during backfill), the latest sync run, and a backfilling flag. The
panel shows a "Backfilling… N captured so far" banner + an Emails Captured count
and auto-refreshes every 5s while a backfill is in progress. Verified live in
preview with seeded data (count auto-climbed 37 -> 50 without manual refresh).
