feat(mobile): stage 3 - home, groups, notifications

- migrate HomeMobile.vue (status card, current session, groups, popular games)
- migrate GroupsMobile.vue (list + create/join popup + pull refresh)
- migrate NotificationsMobile.vue (invitations/join-requests tabs + app notifications)
- router: wire Home/MobileGroups/MobileNotifications mobile views
- verified: user/group/team/notification stores + groups/invitations APIs all match uat

note: event board NOT added to home (uat PC Home.vue doesn't integrate it either);
      events will be handled in stage 11 group detail tab

build verified: vue-tsc + vite build pass
