Update search indexes for Dashboards and Panels to Ferret, plus various minor fixes

Summary:
Depends on D20410. Ref T13272. Dashboards/Panels currently use older "ngram" indexing, which is a less-powerful precursor to Ferret. Throw away the ngram index and provide a Ferret index instead. Also:

  - Remove the NUX state, which links to the wrong place now and doesn't seem terribly important.
  - Add project tags to the search result list.
  - Make the "No Tags" tag a little less conspicious.

Test Plan:
  - Indexed dashboards and panels.
  - Searched for dashboards and panels via SearchEngine using Ferret "query" field.
  - Searched for panels via "Add Existing Panel" datasource typeahead.
  - Searched for dashboards via "Add Menu Item > Dashboard" on a ProfileMenu via typeahead.
  - Viewed dashboard NUX state (no special state, but no more bad link to "/create/").
  - Viewed dashboard list, saw project tags.
  - Viewed dashboards with no project tags ("No Tags" is now displayed but less visible).
