Make user and project profile links into Maniphest show only open tasks

Summary:
A couple of things here:

  - These links got fixed, but they show all user or project tasks. They should show only open ones.
  - Add an anchor so we jump you straight to the results, since the query UI is like a thousand miles tall now. We might take some other approaches here too, but let's see if this feels reasonable.

Test Plan: Clicked "View Tasks" from Profile and Projects. Executed some queries.

Restore "Unbreak Now" and "Needs Triage" homepage boxes as cusomizable elements

Add a differential.getdiffs method

Summary: I kind of made a mess of the API doing T2784. I figure just adding this is fine but LMK if you'd prefer something like diffquery got cleaned up more to handle this.  Also adds an idx() call as I was getting errors looking at old diffs. Fixes T3823.

Test Plan: used the new api via test console - great success.
