Remove redundant naming prompt and fix Ansible empty-prefix command failure in webrunner

- Replace get_deployment_name_with_options() call with auto-derived wr-{deployment_id}; user already entered engagement name, second naming menu was noise
- Split run_scan.yml single command with conditional Jinja prefix into two when-gated tasks; empty-string prefix from use_tor=false caused Ansible to fail with return code 4
