feat(core): Add indices to many-to-one relations

Relates to #1502. Performance & efficiency improvement for Postgres specifically.

BREAKING CHANGE: Explicit indexes have been added to many-to-one relations used throughout the data
model. If you are using MySQL/MariaDB you should not notice a change from this, since they
automatically add indexes to FK relations. Postgres, however, does not so this change will require
a DB migration.
