Add engine only negative tests that reject an engine_newPayloadV5 whose blockAccessList is the invalid 0x empty-byte-string encoding (an empty BAL must be 0xc0), or is omitted entirely, both expecting -32602 Invalid params. Surfaced on glamsterdam-devnet-6 where there was no hive engine coverage for this.
