Subject: [PATCH] fix: preserve user-defined `app.kubernetes.io/part-of` label

Previously, the Initialize() method unconditionally overwrote the app.kubernetes.io/part-of label with spec.applicationName, even when users explicitly set a custom value in metadata.labels.

Now checks if the label exists before setting it, respecting user-provided values while still defaulting to spec.applicationName when the label is not present.
