When a scan completes, dynamically update the dashboard carousels instead of
requiring a full page reload:
- Listen for bookhoard:scan-complete custom event dispatched by header
- Fetch updated sections from /api/dashboard/sections
- Diff existing book cards by data-media-item-id attribute
- Prepend new items to carousel tracks (afterbegin) to match API sort order
- Create entirely new section DOM for sections that don't yet exist on page
- Remove 'No items' placeholder when items are added
- Scroll carousel to left (scrollLeft=0) so newly prepended items are visible
Also:
- Extract renderSectionHTML() helper from renderDashboardCollections() for reuse
- Add data-media-item-id attribute to book card template for DOM diffing
- Add diagnostic console.log statements for debugging scan-complete flow
