Returns the filter values this tenant accepts — object types, statuses, markets, stores, warehouses and users.

Call this first when building a subscription's filters: the values are tenant-specific, so an order status or market id that exists on one tenant may not exist on another. Send the value of an option in the matching filters list; displayName is for showing a human.

classes is nested because some filters only apply to certain object types. Each entry carries the statuses, sub types, workflow steps and tags valid for that type, plus supports* flags saying whether market, store, store-group, warehouse and property filtering apply to it at all.
