extract build-queue rollup as a shared Preact component

Browse source 
New @hive/shared/jobq-rollup.js (JobqRollup.tsx + jobq-rollup.css),
mirroring JobqGraph's shape exactly: JSX use plus an imperative
mountJobqRollup(container, props) for a plain-.js call site. Fetches
Vec<hive_jobq_wire::StateCount> off `endpoint`, sums Running+Finishing
roots as "running" and Pending roots as "queued", renders nothing when
both are zero. Optional `queueHref` adds a "view queue -> " link.

Swapped dashboard's hand-rolled queue-summary banner (swarm.js) over to
this component instead of keeping two parallel implementations - same
"one shared component" pattern JobqGraph already set for the rebuild
queue tree view. Mounted once into a new #jobq-rollup-section, kept as
a sibling of (not inside) #containers-section since that section gets
replaceChildren()-wiped on every container-state render, which would
tear down and remount a Preact tree on every tick. Refreshed via the
mount handle's .refresh() on rebuild_queue_changed, same as builds.js's
JobqGraph handle.

Also mounted in swarm-ui's /jobs page, above JobqGraph, with no
queueHref (a link back to the page you're already on is noise) - the
literal ask on hyperhive#3364.

Verified: npm run build (whole workspace) and swarm-ui typecheck both
clean, comment-block + issue-ref lints run manually, headless-chromium
screenshots of both the dashboard SW4RM tab and swarm-ui's /jobs page
against mocked /api/jobq/rollup payloads - banner renders identically
in both, with and without the queue link as expected.
