fix(web-app-shopware): click through Keycloak's logout confirmation

Shopware's in-app logout leaves the browser on Keycloak's end-session page, which asks 'Do you want to log out?' because the request carries no id_token_hint. The spec waited 60s for a password field that page never renders. The shared persona helper already handles this for inAppLogout; it is now exported so the role-local spec can use it too.

Evidence: the error-context of job 95119330653 shows heading "Logging out" and button "Logout" where the login form was expected.
