Refactor code for improved readability in biometric deduplication service and unit tests

- Cleaned up the formatting of list comprehensions in `biometric_deduplication.py` for better clarity.
- Adjusted indentation in the test case for `test_create_single_individual_success` in `test_lax_individuals.py` to enhance readability.
