Pull request overview

This pull request updates the nginx-coraza connector to use the latest libcoraza API. The changes introduce a two-phase WAF initialization pattern where configuration objects are created first, rules are loaded into the config, and then WAF instances are created from the configuration.

Key changes:

• Split WAF creation into config creation and WAF instantiation phases
• Updated intervention processing to use new libcoraza API (removed URL redirect handling)
• Changed from coraza_rules_add for files to coraza_rules_add_file API
• Updated Dockerfile to manually install library files and switch from libpcre3 to libpcre2
