docs(user): update dashboard and bookshelf instructions for sidebar UI

Dashboard:
- Customize Dashboard is opened from the icon button at the right end
  of the Library bar (next to Refresh), and requires a specific library
  selected rather than 'All Libraries'
- Library switching uses the Library dropdown in the bar below the top
  bar (includes 'All Libraries' with counts)
- Collection sections are shown/hidden from the Customize Dashboard
  toggles — the per-collection 'Show on Dashboard' setting is gone
- Mention the hover chevrons for scrolling carousels

Bookshelf:
- Saved filters: document the new toolbar buttons — Filters (opens the
  filter drawer with Apply Filters, Esc, and overlay-click close), Save,
  Load (Saved Filters dropdown with trash-icon delete), and Clear —
  replacing the emoji-labelled Save Filter / Saved Filters buttons
- Tag filtering: filters now live behind the Filters drawer on the All
  Books page
