fix(helm): disable imagePullSecrets and fix typo in production

Changes:
- Disable imagePullSecrets in production (hub-registry-secret doesn't exist yet)
- Add comment with command to create the secret if needed
- Fix typo: 'flase' -> 'false' in autoscaling.enabled

Note: Registry can work without secret if it's public, or create the secret:
  kubectl create secret docker-registry hub-registry-secret \
    --docker-server=hub.peikarband.ir \
    --docker-username=<username> \
    --docker-password=<password> \
    -n peikarband

This resolves the 'Unable to retrieve some image pull secrets' warning.
