Implement custom reminders with multiple VAlarms per event

Major Features:
- Replace single ReminderType enum with Vec<VAlarm> throughout stack
- Add comprehensive alarm management UI with AlarmList and AddAlarmModal components
- Support relative (15min before, 2hrs after) and absolute (specific date/time) triggers
- Display reminder icons in both month and week calendar views
- RFC 5545 compliant VALARM implementation using calendar-models library

Frontend Changes:
- Create AlarmList component for displaying configured reminders
- Create AddAlarmModal with full alarm configuration (trigger, timing, description)
- Update RemindersTab to use new alarm management interface
- Replace old ReminderType dropdown with modern multi-alarm system
- Add reminder icons to event displays in month/week views
- Fix event title ellipsis behavior in week view with proper CSS constraints

Backend Changes:
- Update all request/response models to use Vec<VAlarm> instead of String
- Remove EventReminder conversion logic, pass VAlarms directly through
- Maintain RFC 5545 compliance for CalDAV server compatibility

UI/UX Improvements:
- Improved basic details tab layout (calendar/repeat side-by-side, All Day checkbox repositioned)
- Simplified reminder system to single notification type for user clarity
- Font Awesome icons throughout instead of emojis for consistency
- Clean modal styling with proper button padding and hover states
- Removed non-standard custom message fields for maximum CalDAV compatibility
