Next-Gen WAF request metrics updated

apichanged

We've enhanced the Next-Gen WAF request metrics in the Historical Stats API. The ngwaf_requests_allowed_count and ngwaf_requests_blocked_count metrics now include counts from both Edge WAF and Core WAF, giving you a more complete view of your WAF activity across all protection layers.

Prior change: Add new fields to Next-Gen WAF workspaces

Following change: Add log_processing_region for logging endpoints
