feat(flutter/track-actions): AddToPlaylistSheet picker

Modal bottom sheet listing the caller's user-created playlists (system playlists like For-You are filtered out — they're not user-mutable). Tap a row to pop with the playlist id; consumer (TrackActionsSheet) then calls PlaylistsApi.appendTracks. Empty-state copy: "You haven't created any playlists yet."
