fix(chart): allow setting storageClassName on PVCs (#1261)

The PVC templates rendered no storageClassName and values exposed no key, so clusters without a default StorageClass (or needing a specific class) couldn't install. Add persistence.{data,uploads}.storageClassName, omitted when empty so the default class is still used.

 ## Notes
 - Ingress is off by default. Enable and configure hosts for your domain.
-- PVCs require a default StorageClass or specify one as needed.
+- PVCs use the cluster's default StorageClass. Set `persistence.data.storageClassName` and/or `persistence.uploads.storageClassName` to bind a specific class.
 - `JWT_SECRET` is managed entirely by the server — auto-generated into the data PVC on first start and rotatable via the admin panel (Settings → Danger Zone). No Helm configuration needed.
 - `ENCRYPTION_KEY` encrypts stored secrets (API keys, MFA, SMTP, OIDC) at rest. Recommended: set via `secretEnv.ENCRYPTION_KEY` or `existingSecret`. If left empty, the server falls back automatically: existing installs use `data/.jwt_secret` (no action needed on upgrade); fresh installs auto-generate a key persisted to the data PVC.
 - If using ingress, you must manually keep `env.ALLOWED_ORIGINS` and `ingress.hosts` in sync to ensure CORS works correctly. The chart does not sync these automatically.
