perf(queue): virtualize the queue list (#857)

* perf(queue): virtualize the queue list

Render the QueuePanel queue through @tanstack/react-virtual so the DOM stays
O(visible rows) instead of O(queue length) — a 10k+ Artist Radio queue no
longer creates tens of thousands of DOM nodes. Row logic (reorder DnD, radio/
auto dividers, lucky-mix loader, context menu) is unchanged, just wrapped in
the virtual rows. Auto-scroll to the next track moves out of useQueueAutoScroll
(which relied on every row being in the DOM) to a virtualizer scroll plus an
exact scrollIntoView on the real target row.

Phase 0 of the queue thin-state plan; no store/persist changes.
