fix(telemetry): review findings

- wau/mau trailing scans run hourly and on day finalization, not every tick
- exclusion lookup failures cached 30s so an st outage cannot amplify
- unverified relation filter dropped; player emptiness checked in js
- anonymous unauthenticated read failures no longer logged
- alerts and exclusions ensure supertokens init on cold pods
