Containerize Hush Line

[micahflee]

This containerizes Hush Line.

Follow the new DEV.md instructions to try it out: https://github.com/micahflee/hushline/blob/containerize/docs/DEV.md

The dev instructions are now the same for all platforms since it's all just running in Docker. Ultimately, the container runs python:3.12-bookworm.

Running make dev starts Hush Line in a container. You can see output from the container in that window, and press ctrl-c to quit. The rest of the Makefile commands (like make test, etc.) require the main container to be running to work, and they also do everything in the container.

There's now a folder called volumes. After you start the server, volumes/app/hushline.db will get created (this file isn't track in git). This way you can access the sqlite3 database outside of docker if you need to.

Another big change is database migrations. There were two identical migrations which was causing it all to break, so I deleted one of them. And now, migrations run automatically when starting the server, so you don't have to make a separate migration step. You just add migrations and restart the server, and the db should be migrated.

Now that it's dockerized, actually running this in production needs to change a bit. The simplest way is to run in prod with docker-compose (on a cloud VM or a Raspberry Pi, or whatever), but it will require making a new docker-compose.yaml file with SECRET_KEY and ENCRYPTION_KEY, and possibly other settings changed.

@glenn-sorrentino please test this out and make sure you're able to get it working locally, and also continue development on top of it. It would be good to get this merged first before I continue other work -- like migrating from sqlite3 to postgres, which would be easier to host going forward.

I stopped the container, started it again, and got "An internal server error occurred", though was working the first time running make dev.
