Fix print preview event positioning to respond to hour range changes

- Add print_start_hour parameter to calculate_event_position function
- Implement proper hour offset calculation for events in print mode
- Remove CSS transform hacks for event positioning
- Use dynamic pixels_per_hour for proper scaling with hour ranges
- Increase modal max-width to 1600px for better visibility
- Events now correctly reposition when start/end hours change
