refactor(grasp-audit): split ValidRepo into Sent/Served, add tolerant purgatory

- Rename ValidRepo to ValidRepoSent (announcement sent, may be in purgatory)
- Add ValidRepoServed (announcement queryable after git data pushed)
- Add send_event_and_note_purgatory() for tolerant purgatory detection
- Update fixtures to use tolerant method instead of strict assertion
- Update event_acceptance_policy tests to use ValidRepoServed

This enables tests to pass regardless of purgatory implementation status
while still having explicit purgatory tests that verify the behavior.
