We should provide example of Adobe Edge network server API for target personalization similar to AJO code base experience example https://experienceleague.adobe.com/en/docs/journey-optimizer/using/channels/code-based-experience/configure-code-based-channel/code-based-implementation-samples#server-side-implementation

Open help/dev/implement/server-side/sdk-guides/sample-apps/sample-apps.md and review its existing sample-app structure. Compare it with the linked AJO server-side implementation sample, then add a corresponding Adobe Edge network server API example for Target personalization; done means the example is present and follows the surrounding documentation style.
