tegwick 619fb72a78 perf(api): CUST-WP-0041 — DB indexes, TTL caches, noload on list endpoints
- Migration t7o8p9q0r1s2: indexes on tasks.status, tasks(workstream_id,status),
  workstreams.status, sbom_snapshots(repo_id,snapshot_at)
- workplan-index: 30 s TTL cache + ?refresh param (4171 ms → 16 ms on hit)
- /state/summary: 15 s TTL cache, bypassed on Cache-Control: no-cache
- /topics/: noload(workstreams, decisions, progress_events) (2382 ms → 115 ms)
- /domains/: noload(topics, repos, goals) (2252 ms → 39 ms)
- /repos/: noload(goals) (2222 ms → 599 ms first / fast on repeat)
- conftest: reset TTL caches between tests to prevent bleed-through

"""
Shared pytest fixtures for the state-hub API test suite.
Uses a real PostgreSQL test database (custodian_test) — never mocked.
Set TEST_DATABASE_URL to override the default.
Schema is created/dropped once per session via psycopg2 (synchronous) to
avoid asyncpg "another operation is in progress" errors during create_all.
Tables are truncated between tests for isolation.
