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 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
