shells: a settings page that restarts the shells, with a notification

Settings > Desktop > Shells lists every directory holding a shell.qml,
running or stopped by `qs list --all`, with Restart (Start when it is not
running) per row and a Restart all. Every button runs reload.sh through
Quickshell.execDetached, which leaves the script outside the desktop
shell's process, so restarting desktop from its own settings window
works: the window closes and the new process carries on.

restart.sh wraps reload.sh and sends one notification naming the shells
that came back, or a critical one naming those that did not. Back means
qs lists an instance on the shell's config path under a pid it did not
have before, within 5s; the old instance can linger in the list for a
moment after qs kill. It checks the process, not the config, so a shell
that starts with a broken component still counts as back.

The rows reuse the ai module's AiRow rather than a copy of it.
