v1.2.2: fix hidden TextField value sync & keyboard trigger

- Use mutableStateOf(TextFieldValue) as single source of truth
- Removed key(currentInput) that caused focus loss on each keystroke
- Changed hidden field from 0x0 to 1x30dp for better IME compatibility
- Fixed display: showing inputText.text instead of stale currentInput
- Soft keyboard now shows input text in terminal's last line
