- Sidebar + playlist manager sorts gain both directions with a caret on
the active row (re-select flips); 'recent' keeps the API order
(newest-first — the old reverse was the #657 bug).
- Import now inserts the new playlist optimistically and bounded-retries
until the API lists it (read-after-write lag forced a manual refresh).
- Play later: tracks land at the end of the manual block (after every
play-next/later, before the source resumes); Play next and Add to
queue are untouched. The queue sidebar shows the section divider
(Next in queue / Next up) with drag-math compensation, and the context
menu shows the landing position of each queue action.
