Fix find_fpm_pool_config to work properly on cPanel

- Update find_fpm_pool_config in php-action-executor.sh
- Add proper domain matching for cPool configs
- cPanel names pool configs after the domain, not the username
- Add wildcard matching as fallback
- Function now successfully locates pool config files
- Critical fix for single-domain optimization in Option 4
