fix: resolve 6 integration test failures

1. patterns endpoint: fix query referencing non-existent column
   di.catalyst_type → dir.catalyst_type (column is on document_impact_records)
2. lockouts seed: use relative timestamps (now + 7d) so active lockout
   is always in the future regardless of when tests run
3. create_agent: make slug optional with auto-generation from name
4. create_source: json.dumps(config) + ::jsonb cast for asyncpg JSONB compat
5. approval_expiry: return count as int (len(expired)) not the list itself
6. metrics_consistency: fix test assertion to match API contract
   (total >= active + reserve, not total == active + reserve + unrealized)
