A0 Implementation Engineer e62ece1c06 feat: T03 backend core – FastAPI + DB models + Equipment API + Redis cache + health + tests

- FastAPI app with CORS, lifespan handlers
- Pydantic Settings config (DB, Redis, CORS, SMTP, JWT, Rentman)
- SQLAlchemy async engine + session (DeclarativeBase)
- 6 DB models: EquipmentCache, RentalRequest, RentalRequestItem, Contact, AdminUser, SyncLog
- Pydantic schemas: EquipmentItem, EquipmentDetail, PaginatedEquipment, ContactCreate, ContactResponse
- Redis cache helper: set/get/delete_pattern, rate limiting, equipment key builders
- Equipment router: list (search/category/sort/pagination), detail, categories – all cached
- Contact router: POST with Pydantic validation + rate limiting (5/min)
- Health router: GET /api/health with DB + Redis status
- 28 pytest tests (all pass, 90% coverage)
- Dockerfile, requirements.txt, pytest.ini, test_report.md

Acceptance Criteria Verification

✅ GET /api/health returns 200 with status, db, redis fields
✅ GET /api/equipment returns 200 with paginated response (items, total, page, page_size, total_pages)
✅ GET /api/equipment?search=K2 returns only matching items
✅ GET /api/equipment?category=Lautsprecher returns only matching items
✅ GET /api/equipment?sort=name_desc returns items sorted descending
✅ GET /api/equipment/categories returns 200 with array of category strings
✅ GET /api/equipment/{id} returns 200 with full equipment detail for valid ID
✅ GET /api/equipment/999999 returns 404
✅ Redis caches equipment list (via fakeredis test)
✅ All 6 DB models defined with correct columns and indexes
✅ POST /api/contact returns 201 with valid data
✅ POST /api/contact returns 422 with invalid email
✅ POST /api/contact returns 422 with privacy_consent=False
✅ Rate limiting active (6th request returns 429)

Smoke Test

App starts: python -c 'from app.main import app; print(app.title)' → "HMS Licht & Ton API"
All endpoints tested via ASGITransport with in-memory SQLite + fakeredis
No real Redis or PostgreSQL needed for tests
