healenium/healenium-backend ? reverse-engineered prompt

Build me the backend for a self healing test system that stores and processes healing results in a Postgres database, and runs as a Dockerized service alongside the database.

I want it to be easy to start with docker compose, and I’d like the backend to expose the API needed for saving healed locator data, reading it back, and handling the logic around matching and processing those results. Use the existing API spec files in the repo as the source of truth, and make sure the service can be launched locally with the database initialized from an SQL script.

Please set it up so I can run the whole thing with one command, and include any config or example files needed to make that work. If anything is unclear from the docs, check the current docs online and follow the expected behavior from the API specification.
