Add system resource tracking and download speed estimation to ReticulumMeshChat

- Integrated psutil for memory and network statistics.
- Enhanced app info API to include memory usage, network stats, and download statistics.
- Implemented download speed tracking for files in NomadNetworkPage.
- Added utility functions for formatting numbers and bytes per second.
- Updated frontend components to display new statistics in real-time.
