m3tm3re 4791c91f06 feat(api): add validator, FastAPI app structure, and health endpoint 
Wave 3 tasks complete:
- Task 7: Validator with 4 checks (pflichtfelder, betraege, ustid, pdf_abgleich)
- Task 8: FastAPI app with CORS, exception handlers, JSON logging
- Task 9: Health endpoint returning status and version

Features:
- validate_invoice() runs selected validation checks
- Exception handlers for ExtractionError and generic errors
- GET /health returns {status: healthy, version: 1.0.0}

Tests: 52 validator tests covering all validation rules
