Moves user registration/login before proxy host creation in the
Coraza integration test. The /api/v1/proxy-hosts endpoint requires
authentication, but the script was attempting to create the host
before logging in.
Changes:
- Move auth block after httpbin ready, before proxy host create
- Add -b ${TMP_COOKIE} to all proxy-host curl commands
- Remove duplicate auth block
Fixes CI failure in waf-integration.yml workflow.
