Get Invoices By Filter

Rule-engine-based list endpoint — an alternative to the simple filter.* query params on the plain list endpoint, for building complex AND/OR filter conditions. Get the field key enum for filter_rules from the corresponding Meta Filter endpoint. fields_to_select is restricted to a fixed allowlist of fields: invoice_uid, invoice_no, prefix, associations, reference_no, invoice_title, estimate, job, customer, customer_name, service_contract, invoice_date, invoice_date_dt, amount_paid, amount_due, due_date, due_date_dt, total, tags, invoice_status, custom_fields, custom_field_internal_object, is_deleted, is_active, is_paid, created_by, created_at, updated_at, external_id, external_status, paid_date, time_to_pay, payment_history, business_unit. Supports cursor pagination — pass cursor_pagination: true (or any of cursor/prev_cursor/last_page) to switch response modes.
