Subject: [PATCH] fix: rebuild the idle inhibitor window when outputs change

The Keep Awake toggle attaches a zwp_idle_inhibitor_v1 to a PanelWindow that
is constructed exactly once, inline, inside a Singleton. Nothing recreates it.

When the set of outputs changes (monitor hotplug), Quickshell destroys that
window along with every other screen-bound window. The bar, drawers and
background return because they live inside screen-bound Variants; this one
does not, so it stays gone for the life of the process.

props.enabled is an independent bool and is unaffected, so the toggle keeps
reporting true and the utilities card keeps rendering "Preventing sleep mode /
Active since HH:MM" while no inhibitor object exists at all. The idle timeouts
then fire normally and the session locks, with no indication anything failed.

Hold the window in a Loader and rebuild it on Quickshell.screensChanged so the
inhibitor is reattached once outputs come back.

Requires the QtQuick import for Loader and Connections.
