Add object_by_id_field helper to BaseObject and replace argument definitions

- Created `object_by_id_field` method in `BaseObject` to simplify the declaration of fields
with an `id` argument.
- Replaced all instances of `field ... do` blocks with `object_by_id_field` where fields require
an `id` argument across multiple types.
