Consolidate shared helpers (format_rating, format_swar, tier_style,
format_relative_time) into widgets/mod.rs and screens/mod.rs. Replace
heap allocations with stack arrays and HashSets, parallelize DB queries
with tokio::try_join, wrap schema init in transactions, use OnceLock for
invariant hashes, and fix clippy warnings. Auto-sync on dashboard mount
when last sync >24h ago. All 105 tests pass.

Replace blocking event loop with tokio::select! over EventStream, mpsc
channel, and tick interval. Add message bus architecture with AppMessage
enum for background task results. Implement Dashboard with roster summary
cards and API sync, and Gameday with cascading team/pitcher selectors,
matchup table, and 9-slot lineup management with save/load.
