        Verify that the French tax report raises no warning when T1-T7 taxes are used.
        The report's check compares the sum of A-boxes against the sum of T-base boxes;
        both sides must balance for the warning to be absent.
        Each T-tax shares the `A1` base tag, which is what links them to the A-box totals.
        T7's percent (5.0) is arbitrary as it has no predefined value in the localization.
