audit pass 7: ARIA, focus management, and label fixes

CSS:
- Add :focus-visible to sortable th, breadcrumb links, list links, cmd-item,
  combobox-option, typeahead-item, sidebar-sub-link, split-divider, stat-card
- Fix .lt-skip-link:focus to also include :focus-visible for spec compliance

JS:
- Mobile nav: add focus trap (_trapFocus), save/restore trigger focus, fix
  aria-hidden="false" to removeAttribute pattern, add document.contains guard
- Combobox: add aria-activedescendant on _moveFocus; add unique IDs to options;
  clear aria-activedescendant on close; wrap querySelectorAll in Array.from
- Typeahead: add aria-activedescendant on _moveFocus; add unique IDs to items;
  add aria-busy during async search; clear aria-activedescendant on select;
  wrap querySelectorAll in Array.from
- Command palette: add unique IDs to items; set/clear aria-activedescendant
  on move and mouseenter; clear on close
- Lightbox: add document.contains guard on focus setTimeout
- Stats filter: add Enter/Space keyboard handler for role="button" cards

HTML:
- Stat cards: add role="button" tabindex="0" aria-label (interactive divs)
- Advanced filter selects: add id/for associations to all 3 label+select pairs
- Accordion SVG icons: add aria-hidden="true" (decorative)
- Range input: add aria-label, aria-valuemin/max/now
- Wizard form controls: add id/for to all 4 label+input/select pairs
