chore: use port-forward to login to argocd server in E2E Tests

[jgwest]

What type of PR is this?
/kind failing-test

What does this PR do / why we need it:
Some E2E tests are intermittently failing on attempting to log in to Argo CD via Route.

This includes 1-132_validate_sensitive_annotation_masking_test.go which is commonly fairly.

My hypothesis is this is due to Route (or cloud loadbalancer) not becoming available in time on the K8s cluster. For several tests, we can thus shift to using kubectl port-forward to access the server.

• However, some tests are specifically designed to test the Route, and remain unchanged.

Have you updated the necessary documentation?

• Documentation update is required by this PR.
• Documentation has been updated.

Test acceptance criteria:

• Unit Test
• E2E Test

📝 Summary

Summary by CodeRabbit

• Tests
  • End-to-end checks now cover Argo CD access through both service port-forwarding and OpenShift Routes, including terminal streaming and connection-reset scenarios.
  • Port-forwarded test connections include readiness checks and automatic cleanup.
  • Sensitive-annotation masking checks now connect through a local port-forward instead of using the Route.

Walkthrough

E2E fixtures and tests now share helpers for reserving local ports and starting kubectl port-forwards. The default Argo CD login and selected tests use Service forwarding. A Route-specific login helper supports tests that explicitly use the OpenShift Route.

Changes

E2E port-forward and Argo CD access

Layer / File(s)	Summary
Shared port-forward helpers test/openshift/e2e/ginkgo/fixture/portforward/fixture.go	Adds local port reservation and kubectl port-forward startup, readiness detection, output logging, timeout handling, and cleanup.
Port-forward consumers test/openshift/e2e/ginkgo/fixture/gitserver/server.go, test/openshift/e2e/ginkgo/sequential/1-053_validate_argocd_agent_principal_connected_test.go	The Git server and principal connectivity test use the shared port-forward fixture instead of local process-management helpers.
Argo CD Service and Route access test/openshift/e2e/ginkgo/fixture/argocd/fixture.go, test/openshift/e2e/ginkgo/sequential/1-132_validate_sensitive_annotation_masking_test.go, test/openshift/e2e/ginkgo/sequential/1-064_validate_tcp_reset_error_test.go, test/openshift/e2e/ginkgo/sequential/1-059_validate_argocd_agent_terminal_streaming_test.go	Default login and the sensitive annotation test use Service forwarding. The TCP reset test calls the Route-specific login helper. The terminal-streaming test comments identify its Route-based connection.

`cmd.Wait()` goroutine exits before `ready` and fail immediately; on readiness
timeout, kill the `kubectl` process before failing so it cannot leak and retain
the local port.
