Update Employee Information for EOR Contract
Applies partial updates to employee information on an EOR contract. Only accepts documented fields — any undocumented fields will cause a validation error. Updates are permitted only when the contract has a status of `new`, `under_review`, `waiting_for_client_sign`, `waiting_for_eor_sign`, `waiting_for_employee_contract`, `waiting_for_employee_sign`, `awaiting_deposit_payment`, or `rejected`.
