bvandeusenandClaude Opus 5.5 4d95c5d0c2 feat(prometheus): widget template format, checker and renderer (#5690) ...

#5690 "Widget template format: YAML schema, validator and renderer", step 2
of milestone 508 "Prometheus widget templates".

- template_format.check(text) -> Template, or TemplateError with every
  problem, each with its line and what to change. Blocks: states, values
  (of -> share and bar, thresholds as numbers or shares, sparkline),
  times (warn_after / crit_after), table (two labels pivoted), info.
  Anchors/aliases refused, 64 KB cap, YAML's on/off/yes/no flagged.
- template_view.render(template, target, latest, now, history) -> View:
  a verdict naming the worst problem, then each block with its problems
  first (crit, warn, ok, then quiet states). Missing series show as "—"
  and say so; a template whose `expects` prefix the target lacks says so.
- shown_value moves to service.py so the renderer can use it.
