Add product retrieval by department categories and typecasting fixes

- Added methods in `department_categories_o`, `departments_o`, and `categories_o` to retrieve products associated with department categories.
- Updated `productsRoute` and `superuserDepartmentRoute` to fetch department-specific products.
- Fixed typecasting in product price assignments for improved data consistency.
