PR Summary

• Rearranged Port Allocation for app Service
  The mapping for the application service been updated, which effectively changes the route through which the service communicates. The old route was "80:8000", and it has been altered to "8081:8005". This does not affect the SSL encrypted connections because "443:8443" stays the same.

• Changed Port Mapping for db Service
  The port mapping for the database service has also been revised. Previously operating through "3306:3306", the service will now use "3307:3306". The adjustment helps to improve efficiency and to avoid potential clashes with other services.

This PR is not safe to merge. The default ports are what is required for this project. We may update this in the future to support multiple sites running at once, but that will require a much more involved PR.
