Dynamic Plugin UI end-to-end test

[jsmolar]

Description

Add Playwright-based end-to-end tests to validate Kuadrant's Console Plugin UI, covering the most common user scenarios when the plugin is loaded dynamically in the OpenShift Console.

Tests Cases

Overview Page

• Navigate to Overview page and verify all major cards are rendered:
  • Getting Started Resources and links
  • Gateways summary (total, healthy, unhealthy)
  • Gateway content
  • HTTPRoute content
  • Policy content

PR: #850

Policies Page

• Create an AuthPolicy via UI and verify it appears in the list
• Create a DNSPolicy via UI and verify it appears in the list
• Create a RateLimitPolicy via UI and verify it appears in the list
• Create a TLSPolicy via UI and verify it appears in the list
• Delete created policies

PR: #815

Policy Topology Page

• Verify the topology graph renders successfully

More specific end-to-end scenarios (e.g., editing policies, modifying labels, searching etc.) will be implemented in future iterations.
