Subject: [PATCH] feat: enhance LookupInput with visual badges and flicker-free
 detection

- Add Badge component to display autodetection status with color coding
- Show green "Auto" badge when type is detected, red when unknown
- Prevent badge flickering during empty-to-non-empty input transitions
- Increase lock icon size from 14x14 to 16x16 pixels with blue color
- Track input state to manage smooth badge transitions
