it was last in SECTIONS, so it rendered as the tenth row and then stopped —
directly under Messages, with empty panel beneath it. that is the bottom of the
LIST. what it wanted is the bottom of the PANEL, the way Update-all sits in the
plugins nav.
`mt-auto` on a second group, divided by the same border the rows already use. it
holds whether there are ten sections or two, and it does not need a spacer element
to push it down.
the split is a `pinned` flag on the section rather than the nav testing for the
key. which sections are the client's site and which are this plugin's own
machinery is a fact about the section, and the nav should be reading it, not
knowing it. one array still — `sectionFor` and `isSectionKey` have to resolve
every key, and a second exported list is a second place to forget one.
the row body came out into `renderRow` so both groups draw the same row. no
change to what a row looks like.
