Title: Bump axios dependency to 1.15.0 to address critical SSRF / memory-exfiltration advisories

Summary:
This PR updates gulp-reporter's dependency on axios from ^0.18.0 to ^1.15.0 to resolve several critical and high security advisories that currently affect projects depending on gulp-reporter.

Suggested change (package.json):

-  "dependencies": {
-    "axios": "^0.18.0",
+  "dependencies": {
+    "axios": "^1.15.0",
     ...
  }

Notes & testing:

• axios 1.x includes API changes in some areas; run the gulp-reporter test suite and smoke tests for the gulp tasks that use HTTP calls.
• If any internal use of axios requires code changes, update the callsites accordingly.

Rationale:

• Multiple critical advisories are linked to old axios versions; bumping to a patched axios removes the vulnerability in downstream projects.

Suggested reviewer checklist:

• Run npm install and npm test in gulp-reporter.
• Verify that reporters still function with typical gulp pipelines.
• Merge and publish patch version.

If upstream maintainers prefer, I can open this PR and include a small compatibility patch if tests indicate breaking changes.
