Next-Gen WAF: Added top attacks endpoint

apiadded

We've added the Get top attacks for a workspace endpoint to the Next-Gen WAF. This endpoint retrieves data on top attacks for a workspace within a specified time range, with aggregation options for analyzing different attack patterns. Results are sorted by request count and can be used in custom dashboards with the top-attacks widget.
