feat: OLAP status priority functions and query updates (#3156)

* feat: OLAP status priority functions and query updates

- Add v1_status_priority / v1_status_from_priority for v1_readable_status_olap
- Use priority-based aggregation in OLAP task status update queries (EVICTED
  below terminal statuses)
- Migration v1_0_84 and schema v1-olap.sql

Made-with: Cursor

* test: durable eviction tests — replay, cancel after eviction, restore idempotency

- test_eviction_plus_replay, test_evictable_cancel_after_eviction, test_restore_idempotency
- Tighter poll interval for faster test runs

Made-with: Cursor

* fix: flakes

* feedback
