Review can search a chosen database: BGG or RPGGeek, by hand

The automatic cascade only reaches RPGGeek when BGG's board-game search
comes up empty — so every D&D box, which BGG does list as board games,
can never find its RPGGeek entry no matter how many times it is
reopened. Eric hit exactly that and settled for keeping them local.

Match cards now carry an editable query with two buttons, "search BGG"
and "search RPGGeek", which replace the row's ballot with whatever the
chosen database returns (owned counts and ranks attached when
available; if that stats call fails the results still stand and the
degradation is reported). The TUI's (f) re-search falls back to
RPGGeek automatically when the board-game search is empty.
