## What this PR does
After deleting an `OpenBAO` app CR, the StatefulSet data PVC
(`data-<release>-0`)
was left orphaned in the tenant namespace, consuming storage
permanently. The
OpenBAO app renders a Flux `HelmRelease` over the vendored upstream
OpenBAO chart,
and StatefulSet-templated PVCs are never garbage-collected on
StatefulSet deletion
by default — the chart set no `persistentVolumeClaimRetentionPolicy`.
This passes a retention policy through the HelmRelease values. The
upstream chart
renders it onto the StatefulSet from
`server.persistentVolumeClaimRetentionPolicy`
(verified in the vendored `server-statefulset.yaml`) — **not** from
`server.dataStorage.*`:
```yaml
server:
persistentVolumeClaimRetentionPolicy:
whenDeleted: Delete
whenScaled: Retain
```
A `test` target is added to the package Makefile so the new
helm-unittest suite
(asserting the passthrough) actually runs in CI —
`hack/helm-unit-tests.sh` only
runs packages that define a `test` target.
> [!WARNING]
> **Deleting an OpenBAO app now permanently removes its data PVC and the
data it holds.**
> This is intentional and fixes the storage leak. `whenScaled: Retain`
is kept on
> purpose so scaling an HA/raft cluster down does **not** destroy a
member's data —
> only full deletion of the release reclaims storage. Back up before
deleting.
Fixes #3058.
### Release note
```release-note
fix(openbao): set persistentVolumeClaimRetentionPolicy so the data PVC is removed when an OpenBAO app is deleted, instead of being orphaned. WARNING: deleting an OpenBAO app now permanently removes its data PVC and the data it holds (scale-down still retains data).
```

## Summary by CodeRabbit
* **New Features**
* Added configurable PVC retention behavior for OpenBao: storage is
deleted when the release is removed and retained when scaling down.
* **Tests**
* Added a Helm unit testing workflow to run chart/unit tests.
* Introduced assertions to confirm PVC retention settings are correctly
passed through and rendered as expected.
