Remove all user-facing emojis and improve modal styling

This commit enhances the professional appearance of the calendar application by removing all user-facing emojis while preserving debug logging functionality. Additionally, includes modal layout and styling improvements for better usability.

## Changes Made:

### Emoji Removal:
- **Event creation modal tabs**: Removed emojis from all 6 tab buttons (📅 Basic Details → Basic Details, etc.)
- **Modal content**: Removed emojis from alarm types, attachment types, pattern examples, and completion status
- **Theme picker**: Removed emojis from all 8 theme options (🌊 Ocean → Ocean, etc.)
- **Context menus**: Removed emojis from event context menu (edit/delete actions) and calendar context menu

### Modal Styling Improvements:
- **Width expansion**: Increased modal max-width from 500px to 900px (80% wider)
- **Enhanced padding**: Added more padding to modal header (2rem 3rem 1.5rem) and tab content areas
- **Responsive design**: Improved mobile adjustments while maintaining desktop experience
- **Checkbox fix**: Override width inheritance for "All Day" checkbox with auto width and inline-block display

### Form Layout Enhancement:
- **Field reordering**: Moved Repeat and Reminder options above date/time pickers for better workflow
- **Visual consistency**: Maintained clean, professional appearance throughout the interface

The application now presents a clean, professional interface suitable for business environments while retaining full functionality. Debug logging with emojis is preserved for development purposes.
