Insurance Deductible Remaining Calculator accuracy and testing

Formula source

• Remaining before claim = max(0, plan deductible - deductible already met). Deductible applied to claim = min(remaining before claim, current claim allowed amount). Remaining after claim = remaining before claim - applied amount.
