v4: a playlist's editor has a URL, as a dump's has — it opened over the playlist's header as a state of the page, which a reload or a shared link lost, while a dump's editor is /@name/dumps/<slug>/edit. It is now /@name/playlists/<slug>/edit: Edit goes there, and Cancel or Save come back to the page in its place. Both paths render PlaylistDetail at the same place, so the playlist stays loaded, and a new slug keeps the view. Anyone who may not edit it gets the page, a guest the sign-in first. playlistPath takes the view, and parsePagePath reads it, so its link has no preview, as a dump editor's has none.
