refactor: standardize app property names and improve TypeScript definitions

- Updated property names in AppCard.vue, AppDetailModal.vue, AppGrid.vue, and other components to use camelCase for consistency.
- Enhanced TypeScript definitions for props and emits in various components to improve type safety.
- Refactored download status handling in processInstall.ts to align with updated App interface.
- Improved error handling and type definitions in DownloadDetail.vue and related components.
- Added optional properties and refined existing interfaces in typedefinition.ts for better clarity and usability.
