Update paperless-ngx to version 0.25.9 and modify probes

Updated the paperless-ngx Helm chart to version 0.25.9, which
includes a change in the readiness and liveness probes. The probe
type has been switched from HTTP to EXEC, utilizing the curl
command to ensure proper container health checks. This adjustment
provides a more reliable method for checking the application's
availability as traditional HTTP checks may not work correctly when
the service is still initializing or dependent services are not
fully ready. The standard path and port settings have been commented
out to accommodate this change. No breaking changes are introduced,
but users should validate probe functionality in their deployments.
