Fix ArtifactEngine CI test failures by updating nock to v14

[v-abhishera]

Description:

Summary

The ArtifactEngine integration tests fail in CI due to nock@9.1.0 being incompatible with Node 24's stricter stream type checking. This PR updates nock to v14 and fixes related test issues.

Root Cause

The CI pipeline (azure-pipelines-extensions.yml) runs tests on Node 24. nock@9.1.0 uses internal stream APIs that changed in Node 24, causing TypeError crashes in all nock-based integration tests.

Changes

1. Update nock dependency (package.json)

• nock: 9.1.0 → ^14.0.6

2. Fix jenkins integration tests (jenkinsTests.ts)

• Added nock.disableNetConnect() and nock.enableNetConnect('127.0.0.1') in beforeEach — required by nock v14 to properly intercept HTTP requests.

3. Fix proxy integration tests (proxyTests.ts)

• Replaced unreachable host redvstt-lab43:8080 with 127.0.0.1:9011 (the test's own local server) — the old hostname was a decommissioned dev machine.
• Replaced 2 occurrences of deprecated new Buffer() with Buffer.from() — Buffer() constructor is removed in newer Node versions.

Testing

• All 60 ArtifactEngine tests passing locally (npx gulp test --suite=ArtifactEngine).
• No changes to production code — only devDependency and test files.

Files Changed

File	Change
package.json	nock 9.1.0 → ^14.0.6
jenkinsTests.ts	Add nock.disableNetConnect()/enableNetConnect()
proxyTests.ts	Fix URL, replace new Buffer()
package-lock.json	Regenerated

Risk Assessment

Low — Only test infrastructure changes; no production code affected.
