🐛 fix: BDD tests PostgreSQL connection for native execution

- Enhance getPostgresHost() to detect Docker vs native execution
- Use localhost for native execution (PostgreSQL port mapping)
- Use container name for Docker execution
- Fix local CI/CD script to set correct DLC_DATABASE_HOST
- Ensure BDD tests can connect in both Docker and native modes
