Implement complete CalDAV events integration
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. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
