Refactor app.rs by extracting components for better organization

Split monolithic app.rs into focused, reusable components:
- Sidebar component for user info, navigation and calendar management
- CalendarListItem component for individual calendar items with color picker
- RouteHandler component to eliminate duplicated routing logic
- Reduced app.rs from 645 to 338 lines (47% reduction)
- Improved separation of concerns and maintainability
- Clean props-based component communication
