fix(querybuildertypesv5): keep subnormal values finite in roundToNonZeroDecimals (#12157)

The sub-1 branch's scale (10^(-order+n-1)) overflows to +Inf for
subnormal inputs (order below ~-308), and Inf/Inf turned a finite stored
value into NaN — which then serializes as the string "NaN". Same guard
as the >=1 branch got in #12151; adds the unit coverage for both.
