Implement interactive calendar color picker

Browse Source 
Backend enhancements:
- Add calendar_path field to CalendarEvent for color mapping
- Generate consistent colors for calendars using path-based hashing
- Update CalDAV parsing to associate events with their calendar paths
- Add 16-color palette with hash-based assignment algorithm

Frontend features:
- Interactive color picker with 4x4 grid of selectable colors
- Click color swatches to open dropdown with all available colors
- Instant color changes for both sidebar and calendar events
- Persistent color preferences using local storage
- Enhanced UX with hover effects and visual feedback

Styling improvements:
- Larger 16px color swatches for better clickability
- Professional color picker dropdown with smooth animations
- Dynamic event coloring based on calendar assignment
- Improved contrast with text shadows and borders
- Click-outside-to-close functionality for better UX

Users can now personalize their calendar organization with custom colors
that persist across sessions and immediately update throughout the app.
