Add full Docker support

[No767]

Summary

This PR probably has been implemented at long last. Focusing on Docker support, this PR aims to allow for Docker usage for Rodhaj internally. This now provides another option for hosting Rodhaj and would probably make it much easier.

A lot of inspiration is pulled from Immich's Docker Compose files, and helped shape the docker compose files and how everything operates. This is now a possible way to run Rodhaj.

Caution

This PR completely breaks and adjusts the PostgreSQL development server. You will more than likely need to adjust your .env file to use the variables found in docker/example.env. Also the compose file itself is in the docker directory.
