feat(web): improve calendar abacus preview styling

CalendarPreview changes:
- Remove showNumbers display from all abaci for cleaner calendar look
- Increase day abaci scaleFactor from 0.35 to 1.0 (fills grid squares)
- Remove year from month title (shows only month name)

CalendarConfigPanel changes:
- Replace link to /create with inline AbacusDisplayDropdown
- Add preview abacus showing current style (value=12, 2 columns)
- Users can now edit abacus styles directly in calendar page
