Add workflow run link to external plugin intake comments (#1915)

* Add workflow run link to external plugin intake comments

- Include a link to the GitHub Actions workflow run in intake comment
- Helps users trace which action run generated the intake report
- Works for both initial intake and re-run intake flows
- Link appears at bottom of comment for all intake states (passed/failed/quality gates)

* Address PR review feedback on intake comment formatting

- Remove leading spaces from runLink construction to preserve markdown formatting
- Remove unnecessary newline prefix before runLink in quality gates section
- Move workflow run link to the very end of all comment types (after warnings)
- For merged intake comments, append link as final element
- Remove unused runId parameter from applyExternalPluginIntakeEvaluation
