fix(config): Ensure API keys are loaded by orchestrator

- Reverts docker-compose.yml to use volume mount for gemini_api_key.txt, due to format constraints.
- Restores and refines Config.load_api_keys() in config.py.
- **Crucially, calls Config.load_api_keys() at the start of gtm_architect_orchestrator.py to ensure keys are loaded.**
- Adjusts _get_gemini_api_key in helpers.py to prioritize keys from Config.API_KEYS.
- This definitively addresses the 'API Key missing' error by guaranteeing key initialization.
