[release/13.4] Accept dev localhost resource service URLs

[aspire-repo-bot]

Backport of #17639 to release/13.4

/cc @danegsta

Fixes #17659

Customer Impact

We rejected polyglot apphosts with *.localhost domains (as compared to explicit localhost domains) when doing aspire run.

Testing

Smoke tests and new E2E test coverage

Risk

Low, it's a simple extra domain check

Regression?

Yes - in 13.4

✅ No documentation update needed.

docs_optional → bug_fix_restores_documented_behavior

No signals were triggered (signal_count == 0). The only changed source file is src/Aspire.Hosting/Dashboard/DashboardServiceHost.cs (plus two test files), which is an internal fix that expands the local-endpoint check to accept *.dev.localhost hostnames in addition to 127.0.0.1 / ::1 / localhost. This fixes a regression in 13.4 where polyglot app hosts using ASPIRE_RESOURCE_SERVICE_ENDPOINT_URL with *.dev.localhost domains were incorrectly rejected when running aspire run. The existing docs describe aspire run working with polyglot app hosts — this patch restores that documented behavior; no new user-facing surface was introduced.
