fix(tui): constrain dialog option height to single line

[sachnun]

Summary

• Constrain dialog select options to single line height with wrapMode="none" and maxHeight={1}
• Prevents text from wrapping to multiple lines in dialog menus

Why

• Locale.truncate already truncates text, but wrapMode="word" was still causing text to wrap to multiple lines
• This ensures truncation works as intended and keeps all dialog options uniform height
