Show the build id, tame long table cells, and add purposeful motion

The build identifier now sits in the sidebar footer. "Is my deploy actually
live?" was only answerable by opening Session & Security, which is the wrong
place for the first question asked after every deploy.

Error-log rows carry stack traces and full URLs. They stretched their row far
past the viewport and pushed the other columns out of view, which is exactly
where the console is least usable. Values over 70 characters truncate and
expand on click.

Motion is limited to two things that mean something: content arriving
(staggered, so a grid resolves instead of snapping), and a fetch being in
flight — the refresh control spins and the status pill pulses, so a section
that legitimately returns nothing still shows that it tried. All of it is
disabled under prefers-reduced-motion.
