feat: implement frontend for calendar integration (Phase 3 & 4)

## Frontend Implementation

### Meeting Selection & Management
- Created MeetingSelection component for choosing between multiple active meetings
- Shows both active meetings and upcoming calendar events (30 min ahead)
- Displays meeting metadata with privacy controls (owner-only details)
- Supports creation of unscheduled meetings alongside calendar meetings

### Waiting Room
- Added waiting page for users joining before scheduled start time
- Shows countdown timer until meeting begins
- Auto-transitions to meeting when calendar event becomes active
- Handles early joining with proper routing

### Meeting Info Panel
- Created collapsible info panel showing meeting details
- Displays calendar metadata (title, description, attendees)
- Shows participant count and duration
- Privacy-aware: sensitive info only visible to room owners

### ICS Configuration UI
- Integrated ICS settings into room configuration dialog
- Test connection functionality with immediate feedback
- Manual sync trigger with detailed results
- Shows last sync time and ETag for monitoring
- Configurable sync intervals (1 min to 1 hour)

### Routing & Navigation
- New /room/{roomName} route for meeting selection
- Waiting room at /room/{roomName}/wait?eventId={id}
- Classic room page at /{roomName} with meeting info
- Uses sessionStorage to pass selected meeting between pages

### API Integration
- Added new endpoints for active/upcoming meetings
- Regenerated TypeScript client with latest OpenAPI spec
- Proper error handling and loading states
- Auto-refresh every 30 seconds for live updates

### UI/UX Improvements
- Color-coded badges for meeting status
- Attendee status indicators (accepted/declined/tentative)
- Responsive design with Chakra UI components
- Clear visual hierarchy between active and upcoming meetings
- Smart truncation for long attendee lists

This completes the frontend implementation for calendar integration,
enabling users to seamlessly join scheduled meetings from their
calendar applications.

+### Phase 2: Meeting Management (Week 2) ✅ COMPLETED (2025-08-19)
+1. ✅ Updated meeting lifecycle logic with grace period support
+   - 15-minute grace period after last participant leaves
+   - Automatic reactivation when participants rejoin
+   - Force close calendar meetings 30 minutes after scheduled end
+2. ✅ Support multiple active meetings per room
+   - Removed unique constraint on active meetings
+   - Added get_all_active_for_room() method
+   - Added get_active_by_calendar_event() method
+3. ✅ Implemented grace period logic
+   - Added last_participant_left_at and grace_period_minutes fields
+   - Process meetings task handles grace period checking
+   - Whereby webhooks clear grace period on participant join
+4. ✅ Link meetings to calendar events
+   - Pre-created meetings properly linked via calendar_event_id
+   - Calendar metadata stored with meeting
+   - API endpoints for listing and joining specific meetings
