fix: bring the admin pages in line with the rest of the app

- Overview: error-volume bars render (the fills were inline spans), the
  cumulative users chart is scaled to its range and labels it, latencies
  over a second read in seconds, and charts and daily numbers use the
  accent instead of four unrelated colours.
- Labels, table headers and state chips drop the mono caps; queue stat
  values drop the serif.
- Error rows keep their content aligned; row metadata wraps instead of
  truncating every item; "1 term" is singular.
- Errors filter uses the shared segmented control; breadcrumbs include
  Admin; user detail spaces its status and actions, uses the accent for
  Generate and says when no access token is stored.
- The jobs table scrolls inside its card on phones.
- Mock server: admin fixtures for every admin endpoint (ADMIN=1).
