fix(status): address final review findings

F1: after a click the shared Switch writes checked directly, dropping
StatusRow's declarative binding, so an external mode change from waybar
or statusctl no longer moved the switch. Resync via onValueChanged.

F2: the spec claimed hyprctl clients counts idle inhibitors, which is
false for a layer-surface inhibitor; replace with the behavioral
hypridle marker check.

F3: README said the check covers both watch states; it exercises the
activated report and the absent-file down report.

F4: give breakProc an onExited check so a failed breaktimer.sh verb is
visible instead of silent.

F5: drop StatusTile's unused required st property and its injection.

F6: comment the startup-order limit on dndBeforePresentation.
