Fix CI gating: VERSION deploy-only, docs no longer skip deploy

Three bugs in path-based CI gating:
- VERSION and scripts/* triggered frontend+backend tests unnecessarily;
  now classified as deploy-only (scripts/db-* still matches as BE)
- docs-only changes skipped build-and-deploy, but docs are served
  in-app by the Docs surface — every change needs a deploy
- Updated path gating comment block and pipeline header to match
