Fix WordPress unable to connect to database

Browse Source 
Two bugs found:

1. wp-config-docker.php was being copied to /usr/src/wordpress/wp-config-docker.php,
   REPLACING the official WordPress config template. Our file only had security
   hardening settings (DISALLOW_FILE_EDIT, etc.) but no DB constants, auth keys,
   or table prefix. The generated wp-config.php had zero database configuration,
   so WordPress could never connect.

   Fix: Copy our config to /usr/src/websitebox-config.php instead, and load it
   via WORDPRESS_CONFIG_EXTRA=require_once in docker-compose.yml.

2. .user.ini set auto_prepend_file=wordfence-waf.php, but the file didn't exist
   until Wordfence plugin was installed. Every PHP request during initial setup
   returned a 500 fatal error.

   Fix: Add a stub wordfence-waf.php placeholder in the Docker image that gets
   copied with WordPress files. Wordfence replaces it during plugin activation.
