feat(mobile): stage 7 - games library (group-scoped, detail/comments/favorites/add/import)

- rewrite GamesLibraryMobile.vue for uat model (games bound to group, not global):
  group selector + search + platform filter + 2-col grid + add/import entries
- new GameDetailSheetMobile.vue: cover/name/aliases/tags/platform + favorite/edit/delete
  + quick-team + comments list with rating
- new AddGameSheetMobile.vue: name/aliases/platform/tags/cover-upload (bound to group)
- new ImportGamesSheetMobile.vue: bulk import via text (name | platform | tags per line)
- router: wire GamesLibrary mobile view
- diverges from master: uat games API requires groupId (addGame/importGames/getGroupGames)
  vs master's global getPopularGames/searchGames; mobile rewritten to match uat PC behavior

build verified: vue-tsc + vite build pass
