- ImageUploadService::store() now returns /assets/uploads/<token>/<file>
so the URL the upload handler emits matches the new GET route.
- public/index.php registers a dedicated GET /assets/uploads/{userToken}/{filename}
route; the legacy /assets/{kind}/{filename} is kept as a fallback.
- GetAssets reads the upload token from $request->server['__uploads_token']
(the front controller threads it that way) instead of the cookies bag.
- Adds GetAssets unit tests for the upload-token happy path and a
token-mismatch 404, plus a FullFlowTest step that uploads and re-fetches
the asset through the front controller.
