Uploading Helm chart via UI vs HTTP PUT results in different filenames

Uploading a Helm chart via the UI versus uploading via HTTP PUT can result in a different filename for the chart. This can impact both content selector privileges and deployment policy settings.

To reproduce:

1. Take an existing Helm tgz and rename it to something that does not contain the chart-name or chart-version.
2. Upload this Helm chart via a PUT and observe the deployed tgz filename remains unchanged.
3. Now upload the same chart via the UI and observe the deployed tgz filename is <chart name>-<chart-version>.tgz

It would appear the UI upload is forming the tgz name from the name and version defined in the Chart.yaml file, whereas the PUT is not

Expected:

Upload of Helm charts via the UI or PUT should result in the same deployed filename.
