POS Pro subscription gating for cash data access in queries

The cash‑management queries now return data only for locations with a POS Pro subscription – this is reflected in cashManagementLocationSummary and PointOfSaleDevicePaymentSessions.
Likewise, the activePaymentSession and cashDrawer fields on PointOfSaleDevice are now gated by the same POS Pro check.
On the requested‑edit side, CalculateRequestedEditLineItemInput and RequestedEditCreateLineItemInput have been removed and replaced by new grouped input types that support line‑item removals for both computed and requested edits.
The CalculatedRequestedEdit and RequestedEdit types now expose a lineItems field that returns a grouped connection object instead of a flat list of items.
Several new error‑code enums were added to shipping label purchase, subscription, and webhook topics, and an additional localizedMessage field was added to CustomerSegmentMembersQueryUserError.
InventoryCountCreateUserError lost two enum values (INVALID_TAG and INVALID_TITLE) reflecting a change in validation logic.
Developers should update queries, mutations, and error handling logic to account for the new field descriptions, gated data, new input types, and added enums, and test POS Pro‑specific use cases.
