feat: Enhance audio renderer with new features and simplify Android UI indicators

Audio Core:
- Add support for splitter previous volume reset (REV 13+)
- Implement new audio processing time limits (REV 14-15)
- Add voice channel resource limits and effect processing v3
- Support float biquad filters for improved audio quality
- Enhance error handling to prevent audio system crashes

Android UI:
- Simplify FPS, RAM, and thermal indicator views
- Remove complex backgrounds and icons for cleaner display
- Reduce view sizes and improve text-based rendering
- Maintain color-coded status indicators for performance metrics

Core System:
- Improve file system save data space handling
- Enhance kernel synchronization error handling
- Add new error modules and result codes
- Fix potential infinite loops in handle operations

These changes improve audio processing capabilities while providing a cleaner,
more performant Android UI experience.
