feat: add LoginScreen, ScheduleScreen, and EventDetailScreen
Add 3 Compose Multiplatform screens consuming Task 6 ViewModels and
Task 8 components:
- LoginScreen: MyIce title, login button, loading/error states
- ScheduleScreen: AppBar + filter card (4 dropdowns) + event list
with loading/error/empty/refreshing states
- EventDetailScreen: AppBar + recap card + players/staff sections
with amber empty-state card
Use TextButton for Refresh/Logout actions (material-icons-core not
available in this Compose Multiplatform setup). Guard setAccount call
against nullable onSelect callback.
