fix: Docker deployment optimization

- Replace postgres:15-alpine with pgvector/pgvector:pg15 (built-in vector extension)
- Remove init-db.sh (pgvector image includes extension, SQL init script instead)
- Add multi-stage Dockerfile for backend (development/runtime targets)
- Add development stage to frontend Dockerfile
- Update .env.example with correct passwords and Docker-internal URLs
- Add POSTGRES_PASSWORD/REDIS_PASSWORD to .env for Docker Compose
- Use named volume for frontend node_modules
- Add backend healthcheck to docker-compose.yml

.env.example
