feat(logging): add home request-log forwarding support

- Introduced `SetHomeEnabled` to enable/disable request-log forwarding to the home control plane.
- Implemented `forwardRequestLogToHome` for non-streaming logs and `homeStreamingLogWriter` for real-time streaming logs.
- Enhanced `FileRequestLogger` to bypass local logging when home forwarding is enabled.
- Updated server configuration to dynamically toggle home request-log forwarding based on changes.
- Added corresponding unit tests to ensure correct forwarding behavior and fallback mechanisms.
