Add int? PayeeId to CreateExpenseRequest (UpdateExpenseRequest inherits) and to ExpenseListItemDto (so it round-trips to the form). Set e.PayeeId unconditionally in CreateAsync and UpdateAsync so 1099 attribution is independent of VendorPayment vs StaffReimbursement type. Map PayeeId in both DTO projections: the paged-list lambda and GetByIdAsync. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
