Transaction preview seems to ignore 'disable_auth_checks' flag

[yr12345678]

Through some experimenting, it seems that the Transaction Preview call via the Gateway API is ignoring the disable_auth_checks flag, causing transaction previews that require authorization to fail even though the flag is set to true. The exact same request via the Core API produces a succesful transaction preview.

I believe this piece of code where TransactionPreviewRequestFlags is initialized, is where the auth check flag is ignored/forgotten:

babylon-gateway/src/RadixDlt.NetworkGateway.GatewayApi/Services/TransactionPreviewService.cs

Lines 129 to 132 in 6510a5a

	var coreRequestFlags = new CoreModel.TransactionPreviewRequestFlags(
	useFreeCredit: request.Flags.UseFreeCredit,
	assumeAllSignatureProofs: request.Flags.AssumeAllSignatureProofs,
	skipEpochCheck: request.Flags.SkipEpochCheck);

Second this.

we have already fixed that (on develop branch), will be released in next gateway release.
