Five small follow-ups on Phase 1b: - docker-compose.macmini.yml: add the mana-events container with the same shape as mana-credits, expose port 3065, add a Traefik route for events.mana.how, and inject PUBLIC_MANA_EVENTS_URL into the mana-web container so the SvelteKit SSR + browser both reach it. - mana-events: background sweeper that deletes rsvp_rate_buckets rows older than 2h every hour. Without it, long-published events accumulate one row per traffic-hour forever (FK cascade only fires on snapshot delete). - PublicRsvpList: track consecutiveFailures and only show the error banner after two failures in a row, so a single mid-poll network hiccup doesn't flash a 30s error the user can't act on. - apps/mana/apps/web: declare postgres as a devDep (already imported by the e2e spec via pnpm hoisting, now explicit).

/**
|
|
* Periodic cleanup of stale rate-limit buckets.
|
|
*
|
|
* Each (token, hour-bucket) row is only useful for the hour it represents
|
|
* — once that hour is over, the row is just dead weight in Postgres.
|
|
* The FK cascade only fires when an event snapshot is deleted; long-lived
|
|
* snapshots therefore accumulate one bucket row per traffic-hour forever.
|
|
*
|
|
* This sweeper deletes any bucket whose hour is more than KEEP_HOURS old.
|
|
* Conservative window so we don't delete a row another request could still
|
|
* read for the same hour boundary in flight.
