MacOS: fix(network): fixes ArticBase UDP buffer handling on macOS (#1263)

Browse Source 
* MacOS: fix(network): fixes ArticBase UDP buffer handling on macOS

- Set minimum 8KB UDP receive buffer size on macOS for reliable operation
- Add platform-specific buffer size handling with conditional compilation
- Enhance error logging with errno details and buffer size verification
- Maintain backward compatibility with existing buffer sizes on other platforms

Fixes ArticBase controller input reliability issues on macOS by ensuring
adequate UDP buffer capacity for real-time controller data transmission.

* Remove redundant log
