Add a Oracle Card database application
This application only has a single purpose: to provide other applications with Oracle data (information about printed Magic cards).
The content of this app is stored in a separate Sqlite DB for several reasons:
- The content of this database is just an import of another site. We don't need to backup it or save anything.
- This allows us to run the import once and bundle the resulting sqlite file in the Docker image (does not contain anything sensitive).
- If we ever change the production DB to something else (Postgres?) we still will send the Oracle DB to every web server.
