ci: make API endpoint tests gracefully skip when services unavailable

- Add continue-on-error and status tracking to service wait step
- Write services_available flag to status file instead of failing
- Check status file before running API tests and skip if services not ready
- Replace error exits with warnings when services unreachable
- Fix import path in gpu_marketplace.py from cli.utils to cli.aitbc_cli.utils
- Remove excessive blank lines and normalize list formatting in DOTENV_DISCIPLINE.
