feat: add capacityReservationGroupID field to AKSNodeClass CRD

Add support for specifying a Capacity Reservation Group when provisioning
nodes through Karpenter/NAP. The field accepts an ARM resource ID validated
via regex pattern matching the CRG resource format.

The Machine API SDK (armcontainerservice.MachineProperties) does not yet
have the CapacityReservationGroupID field — a TODO tracks plumbing it
through once the RP-side Machine API schema is extended. The field exists
on ManagedClusterAgentPoolProfileProperties but not MachineProperties.

Changes:
- v1beta1 + v1alpha2: new optional CapacityReservationGroupID *string
- CRD YAML + chart templates regenerated via controller-gen
- DeepCopy regenerated
- Machine template builder: TODO comment for future plumbing
- Hash tests: verify field participates in hash (no version bump needed —
  new nil field with IgnoreZeroValue doesn't change base hash)
- CEL validation tests: 10 entries for pattern regex
- Unit tests: field storage, nil default, deep copy correctness
