change(fastapi): unify all model relationship behavior

Now, we allow the direct relationships and their foreign keys to
be set in all of our models. Previously, we constrained this to
direct relationships, and this forced users to perform a query
in most situations to satisfy that requirement. Now, IDs can be
passed directly.

Additionally, this change removes the need for extraneous imports
when users which to use relationships. We now import and use models
directly instead of passing string-references to them.
