fix: change $sequence to string type to support MongoDB UUID7 values

The Document and Row response models were casting $sequence to (int),
which destroyed UUID7 values on MongoDB. On MongoDB, $sequence is the
internal _id field which is a UUID7 string, not an auto-increment integer.
The (int) cast converted UUID7 values like "019c56a9-df6d-73fa-8d48-..."
to 19, making $sequence queries fail validation with 400.
