Test dashboard: full menu system, all-service tests, filtering

- Run tests for all 10 services via per-service pytest subprocesses
- Group results by service with section headers
- Clickable summary cards filter by outcome (passed/failed/errors/skipped)
- Service filter nav using ~nav-link buttons in menu bar
- Full menu integration: ~header-row + ~header-child + ~menu-row
- Show logo image via cart-mini rendering
- Mount full service directories in docker-compose for test access
- Add 24 unit test files across 9 services
