🐛 fix: BDD tests PostgreSQL connection using DLC_* environment variables

- Add getPostgresHost() function to use DLC_DATABASE_HOST env var
- Default to dance-lessons-coach-postgres container name
- Update local CI/CD script to set proper DLC_* environment variables
- Fix Docker Compose test execution to pass correct database config
- Ensure BDD tests can connect to PostgreSQL in both Docker and native modes
