fix: add spaces around operators in f-strings for consistency

The changes add spaces around the `+` operator in f-strings to improve code readability and maintain consistency with PEP 8 style guidelines. This affects test assertions in both `beneficiary_service_test.py` and `group_beneficiary_service_test.py` where beneficiary counts are verified.
