feat(mobile): use cached asset info if unchanged instead of downloading all assets (#1017)

* 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
