Add controller setting and persistence configurations

Updated the `values.yaml` file for the Paperless-ngx chart.
- Added a `controller` setting under the `main` service to specify
  the controller explicitly for better clarity and configuration.
- Removed the annotations under the `ingress.main` section to simplify
  the configuration for better customization, if needed in the future.
- Uncommented and defined `accessMode` and `size` for both the
  `export` and `consume` persistence volumes to ensure proper
  configuration is applied, thereby enabling persistent data storage.

These changes help in improving the chart's configurability
and ensure that default values for persistence settings are applied,
preventing issues with data retention. There are no breaking changes.
