Delete Policy Transaction

Deletes the most recent transaction on a policy, rolling the policy back to its prior version. Only the most recent transaction (highest policyVersion) can be deleted — attempting to delete an older transaction returns a 400 error.

After deletion, the policy state reverts to what it was before the deleted transaction was applied. If the only transaction (NEW_BUSINESS) is deleted, the policy has no remaining transactions.

Required permission: policy:delete
