fix(desktop): route gateway restart / status / update to the active profile

restartGateway, getActionStatus, getStatus, updateHermes and
checkHermesUpdate all hit window.hermesDesktop.api WITHOUT spreading
profileScoped() — unlike their siblings (getModelInfo, setModelAssignment,
grantComputerUsePermissions). _apiProfile tracks the active gateway
profile, and the Electron proxy uses request.profile to pick which pooled
/ remote backend serves the call.

So for a multi-profile or global-remote user, the System-panel "Restart
gateway" (and its status poll, plus Update / status reads) targeted the
primary/default backend instead of the one they're on: the restart hit
the wrong gateway and the poll never saw the action → it looked like
restart silently failed. Single-profile users are unaffected
(profileScoped() returns {} when no profile is active).

Add ...profileScoped() to the five backend-action helpers so they follow
the active profile like the rest of the API surface.
