fix: cross-day drag-and-drop + persist showCalendarProviderIcon setting

- Cross-day drag now works: getEventsForSlot uses drag state's current
  start time to assign the dragged event to the correct day column
- Add showCalendarProviderIcon to Prisma schema, profile API GET/PATCH
  so the setting persists across sessions (was frontend-only before)
- DB migration applied via prisma db push
