feat(app): add a checks display selector and name running services in the sidebar

Checks stopped being a toggle. Showing the icon without its word is a real
third answer rather than half of "off" — the state stays on the row for a
glance and a passing workspace stops paying a word for it on every line — so
it left the boolean row-item record instead of widening it, and a stored
`sidebarRowItems.checks === false` migrates to the new "none".

The services item narrowed to actual services. It used to fall back to any
running command, but a test watcher running says nothing about whether a
workspace is up, and the item now says "Services" so drawing a terminal glyph
under that label was a control lying about itself. It reports the name rather
than the port because the name is what you called it. `health` was already on
the wire and nothing in the sidebar read it, so a failed check now turns the
whole item danger; where several services run, the failing one takes the
single slot, since a healthy one is the unremarkable case and any of them
says "this is up".

That narrowing is why the rename went through the code and the persisted key
rather than stopping at the label: the concept genuinely changed, and a UI
saying "Services" over a `scripts` key is the synonym docs/glossary.md calls a
design error. Both key migrations are tagged COMPAT.

The rest is the sidebar row's geometry. The show-more and new-workspace rows
each carried their own smaller, inset, less-rounded version of a workspace row
— 24pt of left margin, a 14pt icon column, `borderRadius.md`, one fill for
hover and press — which under a column of real rows reads as a mistake rather
than a distinction. They now take the workspace row's geometry, and the
show-more row asks its caller whether it is ending an indented list, because
the two groupings disagree.

Group spacing moved from margin to padding so a collapsed group gives it back
instead of staying spaced for content that is gone. SPACING gained a 0.5 rung
for the 2pt gap between rows.
