Ricardo 55baa7cef5 feat: replace explore deck layout with full-width tabbed design ...

Replace the cramped deck/column layout on the explore page with a
tabbed interface. Three tab types: Search (always first), Instance
(pinned with local/federated badge), and Hashtag (aggregated across
all pinned instances).

- New ap_explore_tabs collection replaces ap_decks (clean start)
- Tab CRUD API: add, remove, reorder with CSRF/SSRF validation
- Per-tab infinite scroll with IntersectionObserver + AbortController
- Hashtag tabs query up to 10 instances in parallel, merge by date,
  deduplicate by URL
- WAI-ARIA tabs pattern with arrow key navigation
- LRU cache (5 tabs) for tab content
- Extract shared explore-utils.js (validators + status mapping)
- Remove all old deck code (JS, CSS, controllers, locale strings)
