The root module's k8s.io/* move from v0.35 to v0.37.1 and
controller-runtime from v0.23 to v0.25.1, its release for Kubernetes
1.37. Two things held them back: the apimachinery fork, which had to be
rebased onto every minor, and the watch handler that from
k8s.io/apiserver v0.36 panicked on the initial-events-end bookmark the
aggregated storages sent to plain watches. Both are gone.
The rest of the upgrades are what these releases require: cel-go
v0.29.2, the etcd client v3.7.0, kube-openapi, structured-merge-diff and
the x/ modules. code-generator moves with the libraries.
Regenerating the strategy CRDs that embed core types adds the
Kubernetes 1.37 fields and follows one removal: the alpha PodSpec field
workloadRef became schedulingGroup upstream. Once the new CRD is
applied, the apiserver prunes workloadRef from every stored strategy it
serves, and the object's next write erases it from etcd. It only ever
took effect behind an alpha feature gate.
The gateway README and the tenantgateway CRD tests cite the
apiextensions-apiserver list-type ratchet at the pinned version; it is
byte-identical in v0.37.1, so only the version they name changes.

This PR bumps the runtime k8s libraries to 0.35 (k8s.io/apiserver,
kube-openapi 20250910) but hack/update-codegen.sh still pinned the
openapi code-generator at v0.34.1.
The 0.34.1 openapi-gen keys the version.Info definition by its Go
import path ("k8s.io/apimachinery/pkg/version.Info"), whereas
kube-openapi 0.35 now resolves that model via the new OpenAPIModelNamer
interface — version.Info{}.OpenAPIModelName() ->
"io.k8s.apimachinery.pkg.version.Info". The key mismatch makes the
aggregated apiserver fatal while building its root OpenAPI spec
("cannot find model definition for io.k8s.apimachinery.pkg.version.Info"
-> klog.Fatalf, exit 255), crashlooping cozystack-api. That takes down
the apps.cozystack.io aggregated API, so the Bucket kind can no longer
be resolved and the backupstrategy-controller HelmRelease install fails,
reddening E2E.
Bump the code-generator pin to v0.35.0 (matching the runtime) and commit
the regenerated artifacts. No hand edits to generated files.

The applyconfiguration code referenced testing.TypeConverter from
k8s.io/client-go/testing, which was removed in client-go v0.34.1.
Root cause: hack/update-codegen.sh called gen_helpers and gen_openapi
but not gen_client, so applyconfiguration was never regenerated after
the client-go upgrade.
Changes:
- Fix THIS_PKG from sample-apiserver template leftover to correct
module path
- Add kube::codegen::gen_client call with --with-applyconfig flag
- Regenerate applyconfiguration (now uses managedfields.TypeConverter)
- Add tests for ForKind and NewTypeConverter functions
