The Kotlin NeuronModule reads NEURON_DATA_DIR to locate the SQLite file.
The stage configmap only had NEURON_DB_PATH/NEURON_STORAGE_PATH which
the Kotlin code doesn't read, causing it to fall back to a temp file
that was wiped on every pod restart.
Adding NEURON_DATA_DIR=/data ensures the server reads from the persistent
PVC-backed /data/neuron.db going forward.
