Conversation
Introduce onchain sender attribution for `createOrder` transactions on EVM networks by appending an ERC-8021 data suffix to the transaction calldata. This allows for improved order attribution without relying solely on `metadata.apiKey`. Update documentation to include sender code details, suffix layout, encoding examples in multiple programming languages, and guidelines for appending the suffix to transactions. Update changelog to reflect this new feature.

Review the logic again as we don't have to encourage the use of keys.
