refactor: move rolegroup ConfigMap build into controller/build/config_map

Relocates build_rolegroup_config_map (plus the jaas_config_file helper and its
Error enum) from resource/configmap.rs to controller/build/config_map.rs,
colocating the ConfigMap assembler with the per-file property builders and
matching the controller/build/config_map.rs layout in hdfs/airflow. Pure move +
repointed caller; no behaviour change (18 tests pass).
