Get better visibility for the WAF with payload logging

What this post added

Introduced and detailed payload logging for Cloudflare's WAF, enabling customers to see which specific fields and values within a request led to a WAF rule match. This includes improvements to the Wirefilter engine to log only matching array indices and partial matches, significantly reducing log volume and improving debugging clarity. The new payload logging also includes 'before' and 'after' context for partial matches to provide more granular debugging information.
