docs(components): verification pass — fix cross-link targets, tag code fences, correct type names

- Fix 15 link-text/target mismatches (ConfigurationDatabase ×8 to Commons,
  NotificationOutbox ×4, ClusterInfrastructure case, HealthMonitoring,
  SiteCallAudit) caught by a link-text-vs-target consistency check.
- Tag 14 untagged code-fence openers (ASCII diagrams/trees, JSON, HTTP).
- Correct 4 type names to match source (ValidationService, HealthReportSender,
  CentralCommunicationActor, DebugSnapshotCommand set).
- Soften Traefik version prose per the style guide.
