patrol settings: describe Watch only for plan-locked installs

The Settings > Patrol "Patrol mode" section told every install to choose a mode
on the Patrol page, but plan-locked (free) installs have no mode choice there —
Watch only is their only mode and the paid modes stay off the free surface. The
copy was tier-blind and sent free users on a fool's errand.

Make the section tier-aware via the canonical patrol autonomy availability
resolver: plan-locked installs now read "This install runs Watch only. Patrol
monitors your infrastructure and reports issues here." while Pro/runtime installs
keep the choose-on-the-Patrol-page redirect. The Open Patrol button stays.
