Aspire.Hosting.Foundry should output a Summary after deployment

[eerhardt]

When deploying an app to foundry:

var builder = DistributedApplication.CreateBuilder(args);

var foundry = builder.AddFoundry("aif-globalazure");
var project = foundry.AddProject("proj-globalazure");
var chat = project.AddModelDeployment("chat", FoundryModel.OpenAI.Gpt41);

var app = builder.AddPythonApp("weather-agent", "./app", "main.py")
    .WithUv()
    .WithReference(project).WaitFor(project)
    .WithReference(chat).WaitFor(chat)
    .PublishAsHostedAgent(project);

builder.Build().Run();

the summary has some general information:

✓ PIPELINE SUCCEEDED

  ☁️ Target: Azure
  📦 Resource Group: rg-tomasso-foundry
  🔑 Subscription: b1d52bec-c8f1-4205-9399-473de1c34b90
  🌐 Location: swedencentral

But it should also include a link to the foundry portal for this project.

The Foundry portal link has been added to the deployment summary in PR #16314.

One note on the URL format: the Foundry portal uses a compact URL format (nextgen/r/{base64Sub},{rg},,{account},{project}/home) that contains commas in the path. This causes problems with terminal link detection — most terminals (Windows Terminal, VS Code integrated terminal, iTerm2, etc.) truncate URLs at commas when Ctrl+clicking.

We've addressed this by percent-encoding the commas (%2C) in the URL path. The alternative was the longer foundryProject/overview?wsid=/subscriptions/.../resourceGroups/.../providers/Microsoft.CognitiveServices/accounts/.../projects/...&tid=... format, but that URL is extremely long and also likely to break in terminals due to length truncation.

If the Foundry portal introduces a shorter, cleaner URL format in the future, we can update to use it.
