Cleanup: remove BLE scanner, rename 10-OBD-Display-2024 to 10-GIF-Tests

- 11-BLE-Scanner removed; its car-test log moved to 12-OBD-Speed/docs
- 10-OBD-Display-2024 -> 10-GIF-Tests (GIF playback experiments)
- the broken LVGL 9 archive was already deleted (unintentionally) in d6982ab
- READMEs and CLAUDE.md references updated; visual check of 80 MHz QSPI /
  RGB565_SWAPPED marked as confirmed
