fix: Reject zero DomainID at preflight in OfferCreate and Payment

[vlntb]

High Level Overview of Change

Context of Change

OfferCreate and Payment accepted transactions with sfDomainID present but set to all zeros. In Debug/ASan builds this triggered the Ledger::read : zero key assertion in permissioned_dex::accountInDomain. In Release builds the malformed transaction was misclassified as tecNO_PERMISSION, charging a fee, consuming a sequence, and writing the failed tx to he ledger.

The fix rejects zero sfDomainID at preflight with temMALFORMED, matching the existing convention for PermissionedDomainSet (which already rejects uint256(0) as malformed).

API Impact

• Public API: New feature (new methods and/or new fields)
• Public API: Breaking change (in general, breaking changes should only impact the next api_version)
• libxrpl change (any change that may affect libxrpl or dependents of libxrpl)
• Peer protocol change (must be backward compatible or bump the peer protocol version)
