Refactor API route setup and enhance modularity

- Consolidated API route definitions by registering routes from separate modules for better organization and maintainability.
- Removed redundant route definitions from the APIServer class, improving code clarity.
- Updated camera monitoring and recording modules to utilize a shared context manager for suppressing camera SDK errors, enhancing error handling.
- Adjusted timeout settings in camera operations for improved reliability during frame capture.
- Enhanced logging and error handling across camera operations to facilitate better debugging and monitoring.
