feat(bootstrap): add CSV config loading and improve legacy mode handling

Added functionality to load configuration from CSV files in S3 when available, with fallback to existing methods. The changes include:

1. Added new `load_config_from_csv` method to handle CSV config loading
2. Improved legacy mode handling by attempting CSV load before falling back to database
3. Added new dependencies (uuid, Arc, Mutex) for config management
4. Enhanced error handling and logging for config loading scenarios

The changes maintain backward compatibility while adding the ability to load configurations from CSV files stored in S3, which provides more flexibility in configuration management.
