feat: AutoEQ, speaker EQ enhancements, and audio performance fixes

- Add 16-band graphic equalizer with legacy EQ mode
- Add speaker measurement and room correction EQ
- Fix audio skipping with AutoEQ on Android background
- Improve audio performance to prevent skipping under CPU load
- Fix dual EQ applied when switching between legacy and parametric modes
- Remove redundant Equalizer settings tab
- Improve mobile EQ band layout and collapsible database section
