fix: double date picker on mobile, sidebar scroll, 2-column grid

- Prevent desktop SimpleDatePicker from rendering on mobile (was
  showing two date pickers simultaneously)
- Add overflow-y: auto to settings sidebar at 768px breakpoint so
  the quick actions panel and content are scrollable on all mobile
- Add cols-2 CSS rules for weekly-days-grid and all-day-events-grid
  so the 2-day view spreads columns correctly
