refactor: extract multi-package logic into reusable composables

- Create usePackageSelection composable for installation state management
- Create usePackageStatus composable for status priority logic
- Refactor InfoPanelMultiItem to use new composables
- Reduce component complexity by separating business logic
- Improve code reusability across components
