Which issue(s) this PR closes:

• Closes Collection Page: show lock/unlock icon for restricted files in the card #548

  restricted: boolean
  canbeDownload: boolean
  categories?: string[]

Suggestions on how to test this:

1. create a dataset and publish it in JSF
2. upload a file in a published dataset
3. restrict the file in JSF ( this function didn't implement in SPA), and publish dataset again
4. see if the lock icon is shown on collection page in SPA
5. for admin, an unlock icon should be shown
6. log out, a lock icon should be shown
