fix: use diskPressure instead wildcard default helperPod toleration

sbocinec · derekbit · commit e05217007087 · 2025-07-28T00:26:41.000+08:00
The wildcard toleration ('- operator: Exists') is extremly permissive.
Setting is as a default defeats purpose of allowing to set extra
tolerations as part of the helperPod config.

Use "node.kubernetes.io/disk-pressure" toleration instead as it is
already used in many examples and documentation across the codebase.
