docs: switch job list view control to a toggle button

The plan now uses a button that flips its own text and icon (Compact +
ListIcon / Detailed + ViewFullScreenIcon), mirroring the existing
stopAllButton idiom, instead of a "View" dropdown. It sits beside the folder
filter on the same row via a border layout, so the sidebar header keeps its
current height and the toolbar row is untouched.

The label helpers become nextJobListView and viewToggleText, with tests and
the verification steps updated to match.
