Reduce Startup.Configure complexity by extracting pipeline helpers

[Copilot]

Startup.Configure in TransactionProcessor/Startup.cs exceeded the repository's complexity threshold due to inline endpoint registration and diagnostic/logging blocks. This change keeps the request pipeline behavior intact while moving those details into focused private helpers.

• Refactor Startup.Configure

  • Extracted type-map logging into LogTypeMappings()
  • Extracted endpoint wiring into ConfigureEndpoints(IApplicationBuilder app)
  • Extracted token assembly tracing into TraceLoadedTokenAssemblies()

• Preserve pipeline behavior

  • Kept middleware ordering unchanged
  • Kept all mapped endpoints and health check registrations unchanged
  • Kept startup diagnostics intact

• Small cleanup in touched code

  • Normalized the token assembly trace message to remove a corrupted character

public void Configure(IApplicationBuilder app,
                      IWebHostEnvironment env,
                      ILoggerFactory loggerFactory) {
    ConfigurationReader.Initialise(Startup.Configuration);

    if (env.IsDevelopment()) {
        app.UseDeveloperExceptionPage();
    }

    ILogger logger = loggerFactory.CreateLogger("TransactionProcessor");
    Logger.Initialise(logger);

    Startup.Configuration.LogConfiguration(Logger.LogWarning);
    this.LogTypeMappings();

    app.UseMiddleware<TenantMiddleware>();
    app.AddRequestResponseLogging();
    app.AddExceptionHandler();

    app.UseRouting();
    app.UseAuthentication();
    app.UseAuthorization();
    app.UseMetricServer(s => { });

    this.ConfigureEndpoints(app);

    app.UseSwagger();
    app.UseSwaggerUI();
    app.PreWarm();

    this.TraceLoadedTokenAssemblies();
}

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 /home/REDACTED/work/TransactionProcessor/TransactionProcessor/TransactionProcessor.Tests/TransactionProcessor.Tests.csproj --filter VerifyBootstrapperIsValid --no-restore -nologo (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)
  • Triggering command: /usr/bin/dotnet dotnet restore --no-dependencies /home/REDACTED/work/TransactionProcessor/TransactionProcessor/TransactionProcessor.sln --packages /tmp/codeql-scratch-7ae8d40573b4aa77/dbs/csharp/working/packages /p:DisableImplicitNuGetFallbackFolder=true --verbosity normal /p:TargetFrameworkRootPath=/tmp/codeql-scratch-7ae8d40573b4aa77/dbs/csharp/working/emptyFakeDotnetRoot /p:NetCoreTargetingPackRoot=/tmp/codeql-scratch-7ae8d40573b4aa77/dbs/csharp/working/emptyFakeDotnetRoot /p:AllowMissingPrunePackageData=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)
