fix(workspace): restore playlist info entry in header playlist dropdown (#1328)

The context-actions section of the playlist switcher lost its "Playlist
info" button when playlist actions moved into the per-row menu
(156c12c51): the showPlaylistInfo input, the playlistInfoRequested
output and the whole shell wiring stayed alive, but no template rendered
the entry anymore — the active playlist's info dialog was only reachable
by locating its own row in the list.

Render the button again, gated on the existing showPlaylistInfo input,
alongside Account info and Add playlist. Regression test asserts all
three context actions render in the opened menu and that clicking
Playlist info emits.

+The playlist dropdown in the header shows a "Playlist info" entry for the
+active playlist again, next to "Account info" and "Add playlist" — it had
+disappeared when playlist actions moved into the per-row menu.
