fix(csv-loader): handle object foreign keys in reverse lookups

Browse Source 
Update `csvToModule` to check if a foreign key value is an object
containing the default primary key before converting it to a string.
This ensures correct key mapping when references are resolved as
objects rather than primitive IDs.
