aspire Add playwright test for changing theme

Aspire.Hosting.Tests/Dashboard may not be the best place to put this test long-term. I made it local only for now.

I was unable to access the dashboard frontend from a browser when trying the approach in Aspire.Dashboard.Tests of just creating the dashboard frontend app - it would not connect. If anyone has an idea why that might be, I'm all ears.

I also ran into gRPC issues after orchestrating. Also seeking feedback on that, but in the meantime I injected a mock dashboard service so that there is no grpc connection.

FYI, I'm adding some playwright based tests in https://github.com/dotnet/aspire/pull/3270 . But in that I'm using dotnet run to start up a real app, and then interact with it.

This waits for the dashboard to become available, and uses resiliency to handle retries - https://github.com/radical/aspire/blob/5a900f1f44018a84e6741c45c4d632a1b6e35090/tests/Shared/WorkloadTesting/AspireProject.cs#L408-L427 .

And this connects with playwright, and verifies that the expected resources show up on the dashboard.

@kvenkatrajan we are going to use Ankit’s e2e infrastructure so 90% of this pr content will be replaced :)

thanks for working together on this, sounds like we'll end up with a single infrastructure and it will be easier for everyone.

(when you have your new PR could you check whether any of the feedback above still applies?)
