Remove __networkPolicyForwardRules field from VM config schema

BreakingBreaking change

This is a breaking change — integrations that rely on the affected behaviour will need updates before the change rolls out.

What changed

The __networkPolicyForwardRules property has been removed from two locations in the request body schema (both the create and update paths for VM/sandbox configurations). Any client currently sending this field to configure network forwarding rules — including domain patterns and forwardURL values — will no longer have those rules accepted by the API. This is a breaking change for integrations that relied on this field to set up proxy/forward rules for VM network traffic.
