feat(dashboard): the UGC page replaces UGC Search

The UGC Search page and the UGC page searched the same things (owner,
account, property, the name and description a player gave a model, LOT,
UGC / blueprint id) with the same SQL. The UGC page's lists are now the
one search:

- models' List view has a Where column: placed on a property (with the
  name given there and a link to the model in the property's 3D view),
  in a mail or in the creator's inventories, or not found
  (/api/ugc?where=1, UgcLinks::Whereabouts as before)
- owners link to their character and, with accounts_view, account
- while searching, the kind buttons say how many models and how many
  cars and rockets match (/api/ugc "matches")
- /ugc_search?q= redirects to /ugc?view=list&q=; the menu's UGC Search
  entry is now UGC, which opens the UGC page (it was only under Server
  Admin, for ugc_manage)
- References lose their Find button (Where it is has the same) and name
  the inventory a build is in

The ugc-search page and script are removed; /api/ugc_links/search stays
for API users.

Check: the menu's UGC entry; an old /ugc_search?q= link opens the UGC
list with the search filled in; owner:, account:, property:, name:,
lot: and id: searches, and the counts on the kind buttons; the Where
column's links (property, 3D, character, account).
