feat(ui): make stat numbers clickable to open games

StatDrill context holds one dialog for a page. StatCount wraps a number:
total and status counts link to the library filter, other numbers open
StatGamesDialog. DrillRow and DrillButton support drill-down in tag bars
(genres, platforms, moods) and other stat displays. Dialog shows 40 games
per page with bottom-sheet layout on phones, handles pagination and errors
(403 not shared, 401 expired, 400 bad argument).
