Remove unnecessary exports of file-local helpers

Remove the `export` keyword from functions that are only used within
their own file and are not part of any package's public API:

- `parseStringsParam` and `isOrder` in notifications-backend
- `toWeb` in backend-defaults urlReader
- `resolvePublicPath` in app-backend
