Add comprehensive E2E tests for overload selection visual refresh
Created two E2E tests: 1. SelectOverload_ShouldRefreshNodeVisually - Tests that selecting an overload updates the node visually without F5 2. SelectOverload_ShouldAllowConnectingToNewPorts - Tests that ports are accessible after overload selection Tests use Console.WriteLine which has multiple overloads and verifies the fix works correctly.
