Expand test coverage for SCORE2 algorithm

[fbraza]

Issue Description

Current test coverage for SCORE2 is limited to only 2 test cases, both for 50-year-old smokers.

Current Coverage

• 50-year-old female smoker
• 50-year-old male smoker

Missing Test Cases

1. Non-smokers

• Male and female non-smokers at various ages

2. Different Age Ranges

• Age <50 (different risk thresholds)
• Age 50-69 (different risk thresholds)
• Edge cases: age 40, 49, 50, 69

3. Edge Cases

• Minimum biomarker values
• Maximum biomarker values
• Boundary values for risk categories

4. Error Conditions

• Age outside 40-69 range
• Invalid biomarker values
• Missing required fields

Suggested Test Structure

@pytest.mark.parametrize(
    "filename,expected",
    [
        # Existing tests
        ("test__output__patient_25.json", (50.00, 4.34, "Low to moderate")),
        ("test__output__patient_26.json", (50.00, 6.31, "High")),
        
        # Non-smokers
        ("test__output__patient_nonsmoker_male.json", (55.00, 2.15, "Low to moderate")),

        ("test__output__patient_age_69.json", (69.00, 12.34, "Very high")),
        
        # Edge cases
        ("test__output__patient_high_risk.json", (65.00, 15.67, "Very high")),
    ],
)
def test_score2(filename, expected):
    ...
    
def test_score2_age_validation():
    """Test that age validation works correctly."""
    with pytest.raises(ValueError, match="ages 40-69"):
        compute.cardiovascular_risk("test__invalid_age_30.json")

Impact

• Ensures algorithm correctness across different scenarios
• Validates edge case handling
• Improves confidence in the implementation
