fix: guard remaining BigInt(float) crash sites in per-row WASM data registration

Previous fix (696c270) guarded filter parameter values but missed 3 per-row
data conversion sites: operators.ts int64 filter/range buffer registration
and wasm-engine.ts int-to-int64 promotion. BigInt(3.14) throws RangeError.
