#5689 "Prometheus target page: fold state sets, show epoch times, size
bytes", step 1 of milestone 508 "Prometheus widget templates".

- A state set (name ending in _state, a state label, every series 0 or 1;
  or the OpenMetrics form, the label named after the metric) reads as one
  row per thing it describes, naming the current state, the others on
  hover. fabledarchives_jobs{state} is a count and stays as it is.
- label_pairs / state_label / fold_states in service.py, for the widget
  templates to reuse.
- After a good scrape, series it no longer has lose their newest value
  (forget_gone): Archives' old build_info row read as current beside the
  new one. History stays; a failed scrape forgets nothing; alert rules keep
  their own last-sample time.
- Epoch times and _bytes sizes were already read by shown_value /
  metric_value.

bvandeusenandClaude Opus 5.5 002181253e fix(prometheus): the list page is a section top; the scrape test builds its text without format(); docs (#5668, #5670)
- tests/test_breadcrumbs.py: the Prometheus target list is its section's
  own top page, like SNMP's, so it carries no trail.
- The integration test's exposition has label braces, which str.format read
  as fields: the fake scrape raised, the target was recorded down and no
  series landed. It substitutes the counter with replace() now.
- docs/plugins/prometheus.md: adding a target, filtering, how series are
  named and stored, alerting, and the Fabled Archives recipe.
