Add full M3Y support and fix QR scanning issues for GM65 and M3Y (#335)

- Implement full M3Y scanner support (light, aim, sound, read/stop commands,
  serial mode, high-speed baudrate, and factory reset)
- Improve QR data reading with end-of-line validation to ensure complete frames
- Fix scanners stopping while reading animated QR codes
- Fix GM65 failing to read single large QR codes by increasing UART buffer
  from 2048 to 4096 bytes
- Fix rare LVGL recolor markup line-break issue in animated Specter pMofN QR
  progress that caused hex color codes (e.g. 00F100) to render incorrectly

Closes #314
