Restore OAuth endpoints in Identity OpenAPI

[PANiXiDA]

What changed

• updated PANiXiDA.Core.Presentation.Http from 2.0.6 to 2.0.7;
• added a functional regression test that verifies all OAuth /connect/* paths are present in /openapi/identity.json;
• allowed the functional test factory to create a dedicated Development host for development-only OpenAPI endpoints while keeping all existing tests in Test.

Why

Version 2.0.6 did not attach HTTP module metadata when endpoint groups used the custom RouteGroupBuilder overload. The module-specific OpenAPI filter therefore excluded the OAuth group from the Identity document and Scalar navigation.

Version 2.0.7 attaches the registered module metadata to custom route groups, restoring OAuth endpoints in the Identity API document.

Verification

• dotnet restore PANiXiDA.TacticalHeroes.slnx
• dotnet format PANiXiDA.TacticalHeroes.slnx --verify-no-changes --no-restore
• dotnet build tests/Identity/PANiXiDA.TacticalHeroes.Identity.FunctionalTests/PANiXiDA.TacticalHeroes.Identity.FunctionalTests.csproj --configuration Release --no-restore
• resolved package version: 2.0.7
• CI run 30749341472: all test projects, aggregated reports, and coverage threshold passed
• local tests were not run by request

Compatibility

• migrations: none;
• request and response contracts: unchanged;
• configuration changes: none;
• breaking changes: none.
