Complete drag-to-create event functionality with proper timezone handling

Browse Source 
Integrate drag-to-create functionality with the full event creation pipeline:

- Connect WeekView drag events to CreateEventModal via callback chain
- Add event creation request callback through Calendar → RouteHandler → App
- Implement proper timezone conversion throughout the entire flow
- Fix pixels_to_time calculation (1px = 1 minute, not complex formula)
- Add initial_start_time/initial_end_time props to CreateEventModal
- Convert local times to UTC in both event creation and update functions
- Ensure modal displays correct local times while backend receives UTC
- Support both temporary drag events and real server events in modal

The complete flow now works: drag selection → modal with correct times →
proper UTC conversion → backend storage → correct display in calendar.
