ui: update chip + per-host button

- Surface UpdateAvailable + TargetVersion on the dashboard host row,
  the host_chrome header, and the JSON Host shape.
- New host_update_chip partial renders an amber out-of-date pill
  next to the agent-version display when the host's agent trails
  the server.
- Host detail right-rail gains an admin-only Update agent button
  (disabled when host is offline or already updating).
- New .update-chip and .btn-amber CSS tokens; tailwind output
  refreshed.
