fix: prevent int64 overflow and divide-by-zero in DRA consumable-capacity rounding

roundUpRange computed min + step*n in int64, which overflows to a negative value for near-maximal capacity requests and under-counts consumed capacity (over-admitting a shared device). It also divided by step without checking for zero, and violateValidRange had the same unguarded modulo. Compute the rounded value in big.Int and saturate on overflow, and skip rounding when step is non-positive.
