ee3ae2e81d feat(ai-services): add Vietnamese NLP pipeline for property description analysis 
Implement auto-tagging (amenities, location features, condition/legal),
content quality scoring with moderation integration, and FastAPI endpoints
for single and batch text analysis. Uses underthesea for Vietnamese
tokenization/POS when available, with regex fallback.

811417d77d fix: restrict CORS origins, require payment env vars, replace raw SQL with Prisma findMany 
- AI service: replace allow_origins=["*"] with env-configured AI_CORS_ORIGINS
- Payment services (VNPay, MoMo, ZaloPay): use requireEnv() instead of empty string defaults for credentials
- Search indexer: replace raw SQL template literals with Prisma findMany + parameterized PostGIS queries

- POST /moderation/check — content moderation with rule-based flagging
- GET /health — health check endpoint

Includes Dockerfile (Python 3.12), docker-compose integration, Pydantic models,
and 9 passing tests covering all endpoints.
