feat(playlist): exact-format-per-item selection

Each video row in the playlist panel gets an exact-format button that
lazily probes just that entry's URL (reusing the existing single-video
probe IPC, no new main-process code) and shows a native Select of its
real formats. The choice flows through addMany -> formatId per queue
item. Probing is on-demand per row, never all up front, since a
playlist can hold thousands of entries and per-entry probes are
rate-limited.
