Fix maintainerr config lost after restart: use persistent /addon_configs/maintainerr path

The entrypoint was setting DATA_DIR="/config" which is NOT a persistent
path in HA addon containers using addon_config:rw with init: false.
Changed to /addon_configs/maintainerr (the persistent path mapped by
addon_config:rw in config.yaml), matching the pattern used by the
cleanuparr addon.
