fix(ui): add max-h-60 to layout tab, remove inputMode=decimal from rotation

- Layout TabsContent now matches Layers tab with max-h-60, preventing
  unbounded growth that pushes work tabs off-screen.
- Rotation Input no longer sets inputMode='decimal', which blocked the
  minus sign on mobile keyboards and prevented entering negative angles.
