Add exact multiplier-aware conversions for Solana Token-2022 ScaledUiAmount mints: rawToUiAmountString (ui = raw * multiplier / 10^decimals, exact by construction — the divisor is a power of ten so the expansion terminates) and uiAmountToRaw (inverse, floored to integer base units). All math is BigInt scaled-integer; floats are never used, so results are deterministic across runtimes.
