Add an integration with Zero Hash so users can access crypto onramp and offramp functionality through the product.

Zero Hash is not currently available as an integration option.

Users may manually import a Zero Hash transaction history CSV, or edit related transactions to reconcile history with other wallets.

Manual edits are a temporary workaround and will be overwritten by future fixes or re-syncs. However, manual changes can sometimes result in duplicate transactions or other unintended side effects. For this reason, edits should be made with caution. Once a permanent fix is released, manually edited transactions may need to be reviewed or removed to ensure accuracy.
