fix(server): enforce strict equality (===)

- asset.repository: use === undefined (consistent with other
  visibility checks at lines 709/766)
- bytes: magnitude === 0 for number comparison
- storage-template: asset.type === AssetType.Image

All three were loose == which allows coercion and is flagged by
eqeqeq / type-aware lint.
