Fix otel commands for dev.localhost dashboard URLs

[Copilot]

Description

aspire otel commands can receive AppHost-discovered dashboard API URLs using *.dev.localhost, which may not resolve from the CLI process even though the dashboard is reachable on localhost. This causes telemetry commands such as otel traces, otel logs, and otel spans to fail before contacting the dashboard API.

• Dashboard URL normalization
  • Normalize AppHost-discovered *.dev.localhost dashboard API URLs to localhost.
  • Preserve scheme, port, path, query string, and fragment.

https://nextapp1.dev.localhost:64876/login?t=abc
→ https://localhost:64876/login?t=abc

• Telemetry command coverage

  • Apply normalization before otel commands create dashboard API requests.
  • Normalize dashboard hyperlink URLs returned through the same discovery path.

• Shared MCP path

  • Apply the same normalization in MCP dashboard info helpers so consumers of the auxiliary backchannel use reachable dashboard API URLs consistently.

• Regression coverage

  • Added focused test coverage for a TypeScript-style *.dev.localhost dashboard API URL, verifying telemetry requests are sent to localhost.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• 7k6vsblobprodcus337.vsblob.vsassets.io
  • Triggering command: /usr/share/dotnet/dotnet dotnet test --project tests/Aspire.Cli.Tests/Aspire.Cli.Tests.csproj --no-launch-profile -- --filter-class *.TelemetryCommandTests --filter-not-trait quarantined=true --filter-not-trait outerloop=true (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
