zowe/api-layer — reverse-engineered prompt

Build me a local developer version of the Zowe API Mediation Layer so I can run it on my machine and see how it works end to end. I want one entry point for mainframe style REST services, with a gateway that routes requests, a discovery service that tracks which services are up, and an API catalog UI where I can browse the discovered APIs and their Swagger docs.

Please make it easy to start locally with Java 17 and Node installed, and include a simple run flow that builds everything and starts the full stack. Use the local security setup from the project so I can sign in with the default mock or dummy credentials for development. Make sure localhost HTTPS and certificates are handled the way this repo expects.

If there are sample services in the repo, wire up at least one so it shows up in the catalog and proves discovery is working. If Docker is the smoother path, that is fine too. Look up the current project docs online if you need to.
