v1.2.2: Fix trackball, add display name support, announce with app_data

- Fix trackball completely dead: remove gpio_reset_pin() calls that
  prevented GPIO interrupts from registering on ESP32-S3
- Add trackball left/right tab cycling when screen doesn't consume event
- Add NameInputScreen: Ratspeak-branded first-boot name input
- Add display name to all announces as MessagePack app_data
- Add TEXT_INPUT setting type; expose Display Name in Settings
- HomeScreen Enter key sends announce with toast notification
- Bump version to 1.2.2
