chore(ci): Expand path filters to cover validation inputs

Include templates and test fixtures in lint and test change detection,
verify-bundles.sh in frontend detection, and requirements.txt in docs
detection. Run all validation jobs when release.yaml changes.

Clarify how skipped workflows and matrix jobs affect required checks.

Fixes #23214
