This PR just moves some code around, with the goal of making it easier
to find things in the `collab::db` module. That has become a large
module. Previously, most of the logic lived in one giant `impl Database`
item in `db.rs`.
I broke up this `impl` into several different `impl` blocks, grouped by
topic, each in a different file in a folder called `queries`.
I also pulled out the macro-generated id types into their own file,
moved the `TestDb` struct into its own file, and moved the `sea_orm`
entity declarations into a folder called `tables`.
New folder structure:
```
