Add server-side sync for Kanban board - fixes Task #8

- Added /api/tasks endpoint with file-based JSON storage
- Store now syncs from server on page load
- All changes auto-sync to server
- Added loading indicator while syncing
- Falls back to localStorage if server unavailable
- Tasks #8 now marked as done
