Drop the Actions tab, and give wide panels the width instead of a scrollbar

Four changes from looking at the built page.

ACTIONS HELD ONE CARD. Tracked services was the only thing in it, and it was
the wrong split anyway: a service row reads as state first and a Start/Stop
second, so separating the buttons from the state they act on made a tab that
answered no question on its own. Services move to Metrics, beside the rest of
what the endpoint reports, and the group is gone from the contract.

WIDE PANELS SPAN, THEY DO NOT SCROLL. Network interfaces carries adapter,
address, MAC, speed and state; at half page width in the two-column flow it
either squeezed every cell to three lines or offered a horizontal scrollbar.
A scrollbar for data that just needs room is a layout failure. Table panels
now take column-span, which is the multi-column layout's own answer, so short
fact cards stay two-up around them. The wrapper keeps overflow-x only as a
floor for a genuinely narrow viewport.

SOFTWARE AND ACTIVITY RUN FULL WIDTH. Both are single long lists, and a list
split into two balanced columns reads as two unrelated lists with no way to
tell where the first ended. Details and Metrics keep the two-column flow
because they are short cards, which is what that flow is good at.

Contract 0.29.0 keeps its number: it is unreleased, and the group vocabulary
it introduces has simply lost one value before anybody could depend on it.
