Modify deposit admin view to better reflect metadata-only deposits

Discriminate between source-code deposit and metadata-deposit in moderation/admin view. We need to see clearly what type of deposit. Also the name of column origin is misleading when it comes to deposit of metadata-only.

After the deposit storage has two columns origin-source-code and origin-metadata, the admin view should:

• change origin to uriand insert there the origin-url or the provenance-metadata-url
• add icon that represents if the line is a source-code-depositsor metadata-deposits
• add information if this entry is an update or the first deposit
• add dropdown menu to choose or different tabs (instead of checkbox):
  • all
  • content deposits
  • metadata-only deposits
• add invisible client column
• change directory column name to core SWHID
• change directory with context column SWHID with context
• use icon next to id-column to see metadata (this can also be using a link on the id itself-> see T3376)
• change link on the content of the uri to stay in the WebAPP
• add exit icon to go to the uri location
