📝 WalkthroughWalkthroughThe change centralizes Kubernetes application labels, applies identity and ownership labels to reconciled applications and Kafka resources, standardizes Job and CronJob labels, and broadens deletion discovery across managed-by label versions. ChangesApplication label propagation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to This PR standardizes resource labels and broadens cleanup matching, but it currently fails to apply the intended custom-resource instance labels and can delete unrelated Jobs or CronJobs when labels collide. Merge should be blocked until label assignment and ownership validation are corrected. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Do not delete resources based only on user-controlled labels.
The broadened selectors can match unrelated Jobs or CronJobs in the namespace. A user can create a resource with the same application-name and instance labels. Cleanup then deletes it without checking its controller owner or an accepted managed-by value.

Set app.kubernetes.io/instance from the custom resource name.
BuildIdentityLabels omits AppInstanceLabel. Job and CronJob reconciliation set it to app.Namespace. Both behaviors conflict with the PR objective to use the custom resource name.

Use the package Ginkgo/Gomega suite for these assertions.
Add suite_test.go and migrate these tests from Testify before adding new Test* assertions. Adjacent managed infrastructure packages follow this pattern.
