Disable main controller in Paperless-NGX values

The main controller in the Paperless-NGX Helm chart has been
disabled by commenting out the 'enabled' and 'replicas' options in
the values.yaml file. This change was made to prevent
unintended deployment of the main controller when the chart
is installed or upgraded.

Since the main controller is not currently needed, this will
allow for easier management of resources and prevent any
potential conflicts during deployments. Please ensure that
this change is aligned with the project's deployment strategy.
