* feat(mobile): use cached asset info if unchanged instead of downloading all assets This adds an HTTP ETag to the getAllAssets endpoint and client-side support in the app. If locally cache content is identical to the content on the server, the potentially large list of all assets does not need to be downloaded. * use ts import instead of require
