Refactor MiddlewareRegistry constructor to clear Codacy NLOC warning

[Copilot]

Codacy flagged MiddlewareRegistry::MiddlewareRegistry for exceeding the configured NLOC threshold. This PR reduces constructor size without changing middleware registration behavior.

• Constructor decomposition

  • Extracted health check registration into ConfigureHealthChecks()
  • Extracted Swagger registration into ConfigureSwagger()
  • Kept the constructor focused on orchestration only

• Behavior preserved

  • Integration test and in-memory database branching remains unchanged
  • SQL Server health checks are registered with the same names, queries, statuses, and tags
  • Swagger document metadata, example filters, and XML comment discovery remain unchanged
  • JSON serialization options remain configured exactly as before

• Resulting shape

  • MiddlewareRegistry() now delegates the heavy registration blocks instead of inlining them

public MiddlewareRegistry()
{
    this.ConfigureHealthChecks();
    this.ConfigureSwagger();
    this.AddSwaggerExamplesFromAssemblyOf<SwaggerJsonConverter>();

    this.ConfigureHttpJsonOptions(options =>
    {
        options.SerializerOptions.PropertyNamingPolicy = new SnakeCaseNamingPolicy();
        options.SerializerOptions.PropertyNameCaseInsensitive = true;
    });
}

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:

• f.feedz.io
  • Triggering command: /usr/bin/dotnet dotnet test SecurityService.sln --nologo (dns block)
  • Triggering command: /usr/bin/dotnet dotnet test SecurityService.UnitTests/SecurityService.UnitTests.csproj --nologo -v minimal (dns block)
  • Triggering command: /opt/hostedtoolcache/CodeQL/2.24.3/x64/codeql/csharp/tools/linux64/Semmle.Autobuild.CSharp /opt/hostedtoolcache/CodeQL/2.24.3/x64/codeql/csharp/tools/linux64/Semmle.Autobuild.CSharp (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)
