🐛 fix: BDD tests PostgreSQL connection for native execution

- Simplify getPostgresHost() to always use localhost by default
- Use DLC_DATABASE_HOST=localhost for all local execution
- Container name only needed when running INSIDE Docker containers
- Fix native execution PostgreSQL connection issues
- Ensure BDD tests connect to localhost:5432 (mapped port)
