refactor(searcher): Optimize status card and fix toolbar spacing

- Compact SearchStatusCard layout (80dp → 60dp height)
  - Reduce padding from 12dp to 4dp
  - Smaller icons (24dp → 20dp)
  - Tighter spacing and narrower action buttons
- Fix toolbar height estimates to match actual rendered heights
  - Expanded: 180dp → 164dp
  - Collapsed: 40dp → 44dp
  - Maintains consistent 16dp gap between toolbar and status card
- Fix null safety in FileInfoBottomSheet for optional file sizes
