- transformExpense surfaces invoiced (billed_invoice_id), paid
(supplier_paid), paidAt, paymentMethod, customerAccountId
- updateExpense throws EXPENSE_LOCKED once invoiced (edit until then)
- rebillExpense mints a client invoice line + locks the expense
- markExpensePaid toggles manual paid state
- adminExpenses: POST /:id/invoice (rebill) + POST /:id/paid
- adminTaxReport now gated by accounting master + taxReport sub-flag
(independent of bills; tax export moved out of CRM into Accounting)
