Subject: [PATCH] fix(settings): keep the M3U groups view when every group is
 locked
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With every group locked the filtered channel list is empty, so the
container showed its generic empty state and the groups rail's
"N locked · Enter PIN to show" row never appeared.
