fix(playlists): wrap header action buttons instead of overflowing (#1153)

* fix(playlists): wrap header action buttons instead of overflowing

The Playlists header action row was a fixed flex row, so at narrow
widths (e.g. with the queue panel open) the buttons overflowed and
were clipped off-screen. Add flex-wrap so they wrap, left-aligned,
matching the Albums toolbar behaviour.

* docs(changelog): add 1.49.0 entry for Playlists header button wrap (#1153)
