Character switching, entity ID capture, and UI fixes

- Switch Character now works: send LeaveGame, then re-send LoginRequest with cached token to trigger account screen
- Capture player entity ID from LoadInstance packet to identify own messages and enable LeaveGame
- Fix MsgPackValue Decodable to handle MessagePack timestamp extension types (Date)
- ListBox uses button-based rows instead of Picker (server expects click events, not selection changes)
- Dynamic nav title per buffer tab (Kirandur Global Chat, Map Chat, etc.)
- App icon on login screen via separate Logo image asset
- AsyncStream buffering set to unbounded
