feat(oidc): use the picture claim as avatar when none is uploaded

When a user signs in via OIDC and hasn't uploaded a custom avatar, their
`picture` claim is now used as their avatar. The users.avatar column holds
either an uploaded file name or an absolute https URL from the claim, and a
single resolver on each side (server avatarUrl, client avatarSrc) renders
both. An uploaded avatar always wins and is never overwritten; the picture
refreshes on each login otherwise. Only https URLs are stored, matching the
image CSP.

All the scattered /uploads/avatars/ builders now go through the resolvers,
which also fixes collection member avatars that were rendering a bare file
name.

 ## Notes
 - Ingress is off by default. Enable and configure hosts for your domain.
 - PVCs use the cluster's default StorageClass. Set `persistence.data.storageClassName` and/or `persistence.uploads.storageClassName` to bind a specific class.
+- To use your own PVCs, set `persistence.data.existingClaim` and/or `persistence.uploads.existingClaim`. The other values for that volume (size, storageClassName, annotations) are then ignored.
+- With `persistence.enabled: false`, the data and uploads volumes use an `emptyDir` — storage is ephemeral and lost on pod restart. Intended for testing only.
 - `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.
