Fix client IP logging in Watcher API VirtualHost

Align watcher httpd logging with the cinder/nova-operator pattern:
- Add missing SetEnvIf X-Forwarded-For in the VirtualHost block
- Normalize server-level httpd.conf: use standard LogFormat names
  (combined, proxy), fix inverted env= on proxy CustomLog, log to
  /dev/stdout so logs are visible via oc logs -f
