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. * WIP: Migrate calendar integration frontend to React Query - Migrate all calendar components from useApi to React Query hooks - Fix Chakra UI v3 compatibility issues (Card, Progress, spacing props, leftIcon) - Update backend Meeting model to include calendar fields - Replace imperative API calls with declarative React Query patterns - Remove old OpenAPI generated files that conflict with new structure * fix: alembic migrations * feat: add calendar migration * feat: update ics, first version working * feat: implement tabbed interface for room edit dialog -

Removed grace_period_minutes and last_participant_left_at fields - Simplified deactivation logic based on actual usage patterns: * Active sessions: Keep meeting active regardless of scheduled time * Calendar meetings: Wait until scheduled end if unused, deactivate immediately once used and empty * On-the-fly meetings: Deactivate immediately when empty - Created migration to drop unused database columns - Updated tests to remove grace period test cases * Update test to match new deactivation logic for calendar meetings * fix: remove unwanted file * fix: incompleted changes from EVENT_WINDOW* * fix: update room ICS API tests to include required webhook fields and correct URL -

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. * refactor: rename MinimalHeader to MeetingMinimalHeader for clarity * fix: minor code quality improvements - add emoji constants, fix type safety, cleanup comments * fix: database migration * self-pr review * self-pr review * self-pr review treeshake * fix: local fixes * fix: creation of meeting * fix: meeting selection create button * compile fix * fix: meeting selection responsive * fix: rework process logic for meeting * fix: meeting useEffect frontend-only dedupe (#647) * meeting useEffect frontend-only dedupe * format * also get room by name backend fix --------- Co-authored-by: Igor Loskutov <igor.loskutoff@gmail.com> * invalidate meeting list on new meeting * test fix * room url copy button for ics * calendar refresh quick action icon * remove work.md * meeting page frontend fixes * hide number of meeting participants * Revert "hide number of meeting participants" This reverts commit 38906c5d1a. * ui bits * ui bits * remove log * room name typing stricten * feat: protect atomic operation involving external service with redlock --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Igor Monadical <igor@monadical.com> Co-authored-by: Igor Loskutov <igor.loskutoff@gmail.com>

+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",

+        "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"}
