Add Docker Compose file for Blazor WebAssembly service

This commit adds a Docker Compose file that defines two services: one for the Blazor WebAssembly application and one for the database. The Docker Compose file is used to orchestrate the build, deployment, and scaling of the Blazor app in a containerized environment.

The architecture of this system involves a single container with both services (Blazor app and backend) running within it, but only the Blazor app's configuration has been provided by the user. The Docker Compose file will copy the built Blazor app files and the entry point to the container, expose the port that the Blazor app runs on, and define a health check for the app.

The key components of this architecture are:

* A single Docker Compose file that defines both services
* A container with both services running within it
* Exposure of the Blazor app's port for HTTPS and HTTP traffic
* Health checks to ensure the Blazor app is up and running
