Adds logging of the station manifest to the DB (#90993)

## About The Pull Request
This adds a `manifest` table to the database, basically a databasified
version of the `manifest.txt` log.

## Why It's Good For The Game
This is less of a game feature and more of an admin & Statbus tool. We
currently do not have a good way to see who played which character in a
given round. This aims to fix that.

~~Drafted because I'm not sure on some of the typecasting for the
`special` and `latejoin` columns, I would like someone to give that a
once-over.~~ We good.
