             Summary: Add the FlinkMiniCluster custom resource definition and API types
                 Key: FLINK-40861
                 URL: https://issues.apache.org/jira/browse/FLINK-40861
             Project: Flink
          Issue Type: Sub-task
          Components: Kubernetes Operator
            Reporter: Dale Lane


Adds the {{FlinkMiniCluster}} kind to the operator API module, alongside the existing {{FlinkDeployment}}, {{FlinkSessionJob}}, {{FlinkBlueGreenDeployment}} and {{FlinkStateSnapshot}} kinds, together with a generated CRD, RBAC rules, webhook dispatch and validation.

{{FlinkMiniCluster}} will represent a single Flink job running inside a single pod, with JobManager and TaskManager merged into one JVM process. 

The spec will reuse {{FlinkDeployment}}'s fields wherever the underlying concept is identical (image, flinkVersion, flinkConfiguration, ingress, logConfiguration, serviceAccount and the whole job block), with a single podTemplate and resources block in place of separate jobManager / taskManager blocks, and no native / standalone mode. {{spec.job}} should be required.

The status will reuse jobStatus, lifecycleState, reconciliationStatus and error unchanged. jobManagerDeploymentStatus becomes podDeploymentStatus, carrying the same states.

No existing kind changes shape. Nothing reconciles FlinkMiniCluster resources yet; the controller will be added in a later sub-task.
