Allow administrators to assign a SchedulingClass CR to a tenant.
The schedulingClass is inherited by child tenants and cannot be
overridden once set by a parent.

Add an API-backed listInput dropdown for the schedulingClass field
in the Tenant creation form. The dropdown lists available
SchedulingClass CRs from cozystack.io/v1alpha1.

The label is read by the lineage-controller-webhook to inject
schedulerName and scheduling-class annotation into all pods
in the tenant namespace.

When a namespace carries the scheduling.cozystack.io/class label,
the webhook injects schedulerName=cozystack-scheduler and the
scheduler.cozystack.io/scheduling-class annotation into every Pod.
This covers all workloads in the tenant namespace regardless of
whether the operator CRD supports schedulerName natively.

Before injecting schedulerName and annotation, the webhook now
checks that the referenced SchedulingClass CR actually exists.
If the CRD is not installed or the CR is missing, injection is
skipped so that pods are not stuck Pending on a non-existent
scheduler.

Import SchedulingClassAnnotation, SchedulingClassLabel, SchedulerName,
and GVR components from the cozystack-scheduler/pkg/apis sub-module
instead of defining them locally. This ensures the webhook and scheduler
stay in sync on label/annotation keys.

Also standardize the namespace label from scheduling.cozystack.io/class
to scheduler.cozystack.io/scheduling-class for consistency with the
scheduler, and resolve scheduling class from the owner Application CR
(via a new SchedulingClass() stub method) before falling back to the
namespace label.
