Slow or throwing Entity.toString() and Entity.Id.toString() make YOJ calls slow or failing

...even if tech.ydb.yoj.repository.db logger level is higher than DEBUG, and typically none of the transaction statements ever need to be logged.

You can wreak havoc with a simple entity like this:

@Value
@EqualsAndHashCode(doNotUseGetters = true)
public class BadToStringEntity implements Entity<BadToStringEntity> {
    @NonNull
    Id id;

    @Nullable
    Duration toStringDuration;

    @SuppressWarnings("unused")
    public Duration getToStringDuration() {
        // Mwahahahahahah #1: NPE if a nullable field is null
        Objects.requireNonNull(toStringDuration, "toStringDuration");
        // Mwahahahahahah #2: Delay if a nullable field is not null
        Uninterruptibles.sleepUninterruptibly(toStringDuration);

        return toStringDuration;
    }

    public record Id(@NonNull String id) implements Entity.Id<BadToStringEntity> {
    }
}
