feat(memory): Add memory config API controller and end user info endpoints

- Create new memory_config_api_controller.py for dedicated memory configuration management
- Add /end_user/info GET endpoint to retrieve end user information (aliases, metadata)
- Add /end_user/info/update POST endpoint to update end user details
- Move /memory/configs endpoint from memory_api_controller to memory_config_api_controller
- Extract _get_current_user helper function to build user context from API key auth
- Support optional app_id parameter in end user creation with UUID validation
- Update service controller imports with alphabetical ordering and multi-line formatting
- Register memory_config_api_controller router in service module initialization
- Refactor memory_api_controller imports for consistency and clarity
