Add unique constraints to prevent person_documnt and accompanyingcourse_document with duplicated object_id

This change ensures `object_id` uniqueness within `person_document` and `accompanyingcourse_document` tables. It includes migration scripts and entity annotations to enforce these constraints. This helps maintain data integrity and consistency across the database.
