expense_update
Edits an expense's own fields only — status and approval stamps refuse with VALIDATION_ERROR here since those are transitions (expense_submit, expense_approve, expense_reject, expense_reimburse). amount_cents, if changed, must stay integer CENTS. Only the expense's own creator may edit it, and content freezes once the row is 'pending', reimbursed, or approved by someone else — draft, rejected, and your own self-approved rows stay editable.
