feat(status): add a screen lock mode

dnd and presentation were the only modes, and presentation was the sole
holder of the Wayland idle inhibitor. That inhibitor is the only thing
that stops hypridle's loginctl lock-session at the 600s timeout, so
screen locking is on by default and there was no way to turn it off on
its own.

nolock is stored as "auto-lock disabled" so the file keeps the registry's
"missing means off" rule, and the row inverts it so the switch reads as
the default: lock on. Presentation now drives nolock the same way it
drives dnd, holding the prior value in memory and restoring it on exit,
so it needs no second inhibitor and the inhibitor has a single holder.

The page sets the disable permanently or for a number of minutes. The
deadline and its timer live in the singleton rather than the row because
the drawer page is destroyed on close while the effect has to outlive
it. The timer is shell-lifetime, the same class of limit as
dndBeforePresentation: a restart during a timed disable leaves the lock
off until it is toggled, which is safe because the user opted into the
disable.

The mode governs idle-triggered locking only. The SUPER+l bind and the
lock on suspend are separate paths and stay live.
