refactor: update job execution configuration loading in scheduler

- Implemented dynamic loading of environment variables and configuration settings for job execution, allowing for real-time updates without restarting the gateway.
- Enhanced model and API configuration retrieval from both environment variables and a YAML configuration file, improving flexibility and adaptability of the job execution process.
