fix(search): address review on the shared result rows
- The rows' narrow layout now switches at a 608px list, not 600px. Below
  769px the page pads 1rem each side, so a 640px screen gives a 608px
  list: exactly the old max-width: 640px media query, where 600px left
  633-640px screens on the wide layout.
- rowContainerGuard.test.ts fails if anything other than HomeView renders
  SchoolRow or SecondarySchoolRow, or if one of HomeView's row lists loses
  its `results` container. Outside one the rows silently keep their wide
  layout on phones. (Checked: HomeView is the only importer today.)
- Picking a pin from the list beside the map now works from the keyboard:
  each row carries a "Show <school> on the map" button, visually hidden
  until focused, with aria-pressed for the selected school. The row itself
  cannot be the button, since it holds links and buttons of its own.

/*
* SchoolRow and SecondarySchoolRow switch to their narrow layout with a
* container query on a `results` container, not a media query, because the
* same row fills the phone list and the narrow list beside the desktop map.
* Outside a `results` container the query never matches and the row keeps its
* wide layout on a phone, a silent regression rather than an error.
*
* HomeView provides the container on every list it renders the rows into.
* Anything else that starts rendering them must do the same; this fails so
* that the person adding it reads this first.
