Implement complete CalDAV events integration

Browse Source 
Added full CalDAV integration to display real calendar events from Baikal server:

Backend changes:
- Added CalDAV client with iCalendar parsing and XML handling
- Created /api/calendar/events endpoint with authentication
- Fixed multiline regex patterns for namespace-prefixed XML tags
- Added proper calendar path discovery and event filtering

Frontend changes:
- Created CalendarService for API communication
- Updated calendar UI to display events as blue boxes with titles
- Added loading states and error handling
- Integrated real-time event fetching on calendar load

Now successfully displays 3 test events from the Baikal server with proper date formatting and responsive design.
