feat: calendar integration (#608)

* feat: calendar integration

* feat: add ICS calendar API endpoints for room configuration and sync

* feat: add Celery background tasks for ICS sync

* feat: implement Phase 2 - Multiple active meetings per room with grace period

This commit adds support for multiple concurrent meetings per room, implementing
grace period logic and improved meeting lifecycle management for calendar integration.

## Database Changes
- Remove unique constraint preventing multiple active meetings per room
- Add last_participant_left_at field to track when meeting becomes empty
- Add grace_period_minutes field (default: 15) for configurable grace period

## Meeting Controller Enhancements
- Add get_all_active_for_room() to retrieve all active meetings for a room
- Add get_active_by_calendar_event() to find meetings by calendar event ID
- Maintain backward compatibility with existing get_active() method

## New API Endpoints
- GET /rooms/{room_name}/meetings/active - List all active meetings
- POST /rooms/{room_name}/meetings/{meeting_id}/join - Join specific meeting

## Meeting Lifecycle Improvements
- 15-minute grace period after last participant leaves
- Automatic reactivation when participant rejoins during grace period
- Force close calendar meetings 30 minutes after scheduled end time
- Update process_meetings task to handle multiple active meetings

## Whereby Integration
- Clear grace period when participants join via webhook events
- Track participant count for grace period management

## Testing
- Add comprehensive tests for multiple active meetings
- Test grace period behavior and participant rejoin scenarios
- Test calendar meeting force closure logic
- All 5 new tests passing

This enables proper calendar integration with overlapping meetings while
preventing accidental meeting closures through the grace period mechanism.

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

- 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

- 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

- 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

- 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)

- 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

- 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

- 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.

* fix: add Redis distributed locking to prevent race conditions in process_meetings

- Implement per-meeting locks using Redis to prevent concurrent processing
- Add lock extension after slow API calls (Whereby) to handle long-running operations
- Use redis-py's built-in lock.extend() with replace_ttl=True for simple TTL refresh
- Track and log skipped meetings when locked by other workers
- Document SSRF analysis showing it's low-risk due to async worker isolation

This prevents multiple workers from processing the same meeting simultaneously,
which could cause state corruption or duplicate deactivations.

ICS Calendar Synchronization Service
This module provides services for fetching, parsing, and synchronizing ICS (iCalendar)
calendar feeds with room booking data in the database.
Key Components:
- ICSFetchService: Handles HTTP fetching and parsing of ICS calendar data
- ICSSyncService: Manages the synchronization process between ICS feeds and database
Example Usage:
# Sync a room's calendar
room = Room(id="room1", name="conference-room", ics_url="https://cal.example.com/room.ics")
result = await ics_sync_service.sync_room_calendar(room)
# Result structure:
{
"status": "success", # success|unchanged|error|skipped
"hash": "abc123...", # MD5 hash of ICS content
"events_found": 5, # Events matching this room
"total_events": 12, # Total events in calendar within time window
"events_created": 2, # New events added to database
"events_updated": 3, # Existing events modified
"events_deleted": 1 # Events soft-deleted (no longer in calendar)
}
Event Matching:
Events are matched to rooms by checking if the room's full URL appears in the
event's LOCATION or DESCRIPTION fields. Only events within a 25-hour window
(1 hour ago to 24 hours from now) are processed.
Input: ICS calendar URL (e.g., "https://calendar.google.com/calendar/ical/...")
Output: EventData objects with structured calendar information:
{
"ics_uid": "event123@google.com",
"title": "Team Meeting",
"description": "Weekly sync meeting",
"location": "https://meet.company.com/conference-room",
"start_time": datetime(2024, 1, 15, 14, 0, tzinfo=UTC),
"end_time": datetime(2024, 1, 15, 15, 0, tzinfo=UTC),
"attendees": [
{"email": "user@company.com", "name": "John Doe", "role": "ORGANIZER"},
{"email": "attendee@company.com", "name": "Jane Smith", "status": "ACCEPTED"}
