Custom annotations for Tenant resource #2505

Is your feature request related to a problem? Please describe.
Currently, there is no way to add custom annotations to the Tenant Custom Resource. This is a blocker when using Pulumi, as Pulumi relies on annotations to determine when a resource should be considered ready.

Describe the solution you'd like
I would like to be able to define custom annotations on the Tenant CRD resources. In particular, support is needed for the following annotation:

pulumi.com/waitFor: "jsonpath={.status.phase}=Initialized"

This would allow Pulumi to wait until the Tenant resource reaches the Initialized phase before continuing with further provisioning steps.

Describe alternatives you've considered
There is no viable alternative solution. Without the ability to add this annotation directly to the Tenant resource, it is not possible to implement reliable readiness checks in a declarative and automated way.

Additional context
This is required for proper Pulumi integration and to ensure correct ordering and stability during tenant provisioning workflows.
