The idle inhibitor ("Keep Awake") lives only in memory: SessionService holds it
as a plain `property bool idleInhibited: false` and nothing ever writes it out.
Every restart of the shell silently clears it — the user's explicit choice is
dropped with no message and no trace, and the pill just disappears from the bar.
Restarting is not an edge case. `dms restart` is a first-class CLI command, and
the unit shipped in this repo (assets/systemd/dms.service) sets
`Restart=on-failure` with `TimeoutStopSec=10`, so a shell that is slow to stop
is killed and brought back automatically. Each of those paths turns Keep Awake
off without saying so.
Every other Control Center toggle already survives a restart. Measured on
upstream master, over the state read by Modules/ControlCenter/Components/
DragDropGrid.qml and its neighbours:
doNotDisturb in SessionSpec: yes
isLightMode in SessionSpec: yes
nightModeEnabled in SessionSpec: yes
wallpaperCyclingEnabled in SessionSpec: yes
idleInhibited in SessionSpec: NO
So this follows the doNotDisturb idiom exactly rather than inventing a
mechanism: one spec entry, one property, one setter that saves.
Restore happens through two entry points because the singletons are lazily
created and their order is not fixed: `onLoaded` covers "service instantiated
before the session file is read", `Component.onCompleted` covers the opposite.
enableIdleInhibit() is idempotent, so whichever runs second is a no-op.
The default stays false and SessionStore.toJson omits defaults, so an untouched
session.json gains no new key.
Related: #1483 asks for a configurable timer. The field added here is the same
shape doNotDisturb uses with doNotDisturbUntil, so a later `idleInhibitedUntil`
slots in beside it without another migration.
