Tekton Phase 2 Day 3: Complete Harbor authentication and test build

- Added config.json key to harbor-credentials ExternalSecret
  This ensures kaniko can find the Docker auth config at /kaniko/.docker/config.json
  (previously only .dockerconfigjson was present)

- Created test-app-build PipelineRun manifest for validation testing

- Successfully validated end-to-end pipeline:
  ✅ git-clone Task deployed and working
  ✅ kaniko-build Task deployed and working
  ✅ container-build Pipeline deployed and working
  ✅ Harbor authentication working with robot account
  ✅ Test image built and pushed: the-seas.local.mk-labs.cloud/library/test-app:v1.0.0
  ✅ Image digest: sha256:aa143f4a01795a1d307b711108ca0c89f36e00ea38fddb9d7b2febd5fffc46d7

Pipeline test results:
- PipelineRun: test-app-build-005 - SUCCEEDED
- fetch-repository TaskRun - SUCCEEDED
- build-and-push TaskRun - SUCCEEDED

Tekton CI/CD platform is now operational and ready for production workloads.
