refactor(tui): Use explicit charCode check for unicode filtering

Browse source 
- Use 'charCodeAt(0) >= 32' instead of open 'else' in handleInput()
- Use same filter in handlePaste() for consistency
- Prevents control characters while allowing all unicode
- More explicit and safer than accepting everything
