argus flagged on !2910 that the dashboard doc still described the pill's
old shape. It did, in two ways that now teach the wrong thing:
- it listed a fixed vocabulary, where the label is now the running
node's own wire tag — the `NodeKind::as_str` strings `NodeView.kind`
already carries. A client that switches on specific values is now
wrong, and `restarting` in particular no longer exists at all.
- it described the transient as operator-initiated ("set the moment the
operator clicks"), which was the distinction between it and the
rebuild-queue fallback. That is no longer true: the transient is
derived from the running node, so worker-driven work the operator
never clicked lights the same pill.
The queue-`kind` half of that section is untouched — that path did not
change and its vocabulary is still fixed.
Also notes on the wire-event list that `transient_kind` is a display
string to render, not an enum to branch on, since that is the property a
client would otherwise have to infer from a now-open set.
Docs only, no code change.
