fix: stopped status would never return from that state (#324)

* fix: show C-p groups hint only when group field is focused

The rename dialog bottom hint line showed "C-p groups" on all fields,
but Ctrl+P only works on the group field (focused_field == 1). Add the
same focused_field guard already used in handle_key and group_hint
rendering so the hint matches the actual behavior.

* stop status stuck
