refactor: clean up ui-design.pen — remove befores, integrate design files (#122)
- Remove 2 'before' variant frames (csB01, mb001) keeping only 'after' versions
- Rename 'after' frames to drop Before/After labels (csA01, mb011)
- Integrate 18 frames from 7 design/*.pen files into ui-design.pen:
- 4 full layouts (editor focused, search, properties, changes view)
- 2 add-property-inline, 2 autocomplete-type-color, 2 date-picker
- 1 hide-backlinks-empty (after only), 4 smart-property-display
- 3 status-property-dropdown
- Reposition all integrated frames to avoid overlaps
- Frame count: 113 → 129 (−2 removed, +18 integrated)
- No dark mode conversion needed (all frames use CSS variables)
- No duplicates found (unnamed frames are section dividers)
