fix: KeyboardWidget preview buffer size and KEY_CONTEXT_MENU handling

Browse Source 
- preview[] increased from 32 to 40 bytes to safely fit max label (15 chars)
  + 20 chars text + cursor + null without snprintf truncation
- KEY_CONTEXT_MENU (long-press ENTER) now treated as CANCEL in keyboard
  input handler, restoring BotScreen behavior lost in the refactor
