* TIAAS-12174: fix(keycloak_authentication): handle None authenticationExecutions
When a flow is defined without authenticationExecutions, module.params.get()
returns None but the key still exists in the config dict. The 'in' check
passes but iterating over None raises TypeError.
Guard the iteration with an explicit None check.
