RHIDP-12779: Fix CQA script false positives and apply content fixes

Script fixes (eliminate false positives):
- cqa-05: Allow .Example/.Sample block titles and descriptive labels in
  reference modules; broaden allowed procedure block titles
- cqa-09: Resolve {abstract} attribute references before measuring length
- cqa-12: Only report Vale errors as failures (not warnings/suggestions);
  show issue count instead of "(see output above)"
- cqa-13: Remove assembly body content check (belongs to CQA #6)
- cqa-14: Resolve images via :imagesdir: attribute; skip URLs/YAML
- cqa-17: Skip Technology Preview mentions inside source blocks;
  accept inline mentions with official Red Hat support link

Content fixes:
- Shorten 9 too-long abstracts (auth, service-to-service, tokens)
- Expand 1 too-short abstract (troubleshoot authentication)
- Remove open block markers from 2 abstracts (guest user, s2s auth)
- Fix 8 Vale TermsWarnings (click on→click, like→such as, etc.)
- Fix .Procedure trailing space in sidebar menu localization
- CQA autofix: parent-context preservation in nested assemblies
