atlas 39b95c2ede treefmt: apply prettier
Pure `nix fmt` output from the commit before this one — no hand edits.
203 files: 52 md, 42 tsx, 32 js, 32 css, 21 ts, 13 html, 8 json, 3 mjs.

Reproduce with `nix develop -c nix fmt` on the parent commit; the result
should be byte-identical to this tree.

None of the 13 `.prettierignore` entries appears here — verified by
intersecting the changed-file list against the ignore file, with a
control proving the intersection finds a match when one exists.

// <JobsPage> — the swarm-level job graph. Reuses the shared JobqGraph
// component (originally built for the per-hive dashboard's rebuild
// queue) pointed at swarm-controller's own GET /api/jobq/graph instead
// of hive-c0re's — same wire shape (Vec<hive_jobq_wire::GraphNode>),
// different endpoint, no component fork. swarm-controller's graph has
// no real node kinds wired in yet (see swarm-controller/src/main.rs's
// SwarmNodeKind/SwarmResourceKind), so this renders an empty tree today
// — the page exists so the wiring is in place before the first real
// swarm-level job (e.g. CreateAgent) lands.
//
// JobqRollup sits above the graph, same "N running / M queued" banner
// the dashboard's SW4RM tab shows — no `queueHref`, since a "view
// queue →" link back to this same page would be noise.
//
// Auto-refresh reuses `HivesPage`'s exact pattern (`RefreshIntervalPicker`
// in the `Panel`'s `actions` slot, `useRefreshInterval` driving the
// re-fetch), but ticks a `refreshToken` bump instead of doing its own
// fetch — both `JobqGraph`/`JobqRollup` already accept that prop
// (bumping it is their documented "refetch now" lever) since the
// dashboard's own rebuild-queue view needed the same thing first.
