Add debug logging to shared server handlers

[Copilot]

The Go Logger Enhancement workflow failed before producing a usable change set. This update applies the intended focused logging improvement manually in the shared server handler path the workflow was inspecting.

• Shared handler observability

  • Add debug logs when the /reflect handler is created and when it serves a request.
  • Add debug logs around common endpoint registration so startup wiring is easier to trace.

• Auth-wrapped close endpoint visibility

  • Log when /close is wrapped with API key auth.
  • Log the final set of shared endpoints once registration completes.

• Scope

  • Keep the change limited to internal/server/handlers.go, reusing the existing server:handlers logger.

func HandleReflect(unifiedServer *UnifiedServer) http.HandlerFunc {
	logHandlers.Print("Creating reflect handler")
	return func(w http.ResponseWriter, r *http.Request) {
		logHandlers.Printf("Reflect endpoint request: remote=%s, method=%s, path=%s", r.RemoteAddr, r.Method, r.URL.Path)
		httputil.WriteReflectResponse(w, unifiedServer.DIFCComponents)
	}
}

Pull request overview

This PR improves observability in the shared HTTP endpoint wiring in internal/server/handlers.go by adding debug logs using the existing server:handlers debug logger, making it easier to trace handler creation and endpoint registration during startup and to see when /reflect is exercised.

Changes:

• Add debug logging when the /reflect handler is created and when it serves a request.
• Add debug logging at the start/end of shared endpoint registration to aid startup tracing.
• Add debug logging when /close is wrapped with API key auth.
