Require policy in every overrideAllValues object.

When overrideAllValues is non-empty, the template emits it instead of $mergedEdnsValues, so the stack default policy: upsert-only is not included. ExternalDNS chart 1.22.0 sets its chart-level policy to null, while its schema requires a non-null string. An override that omits policy can therefore fail Helm validation. Add policy: upsert-only to each override or validate this requirement before upgrading.

In `@functions/render/200-external-dns.yaml.gotmpl` at line 56, Ensure every
non-empty overrideAllValues object includes a non-null policy value of
upsert-only before rendering the ExternalDNS chart configuration, preserving the
merged default behavior when no overrides are provided.
