feat: enhance app detail modal to prioritize installed version based on installation status

- Updated `openDetail` function to check installation status for both Spark and APM versions, setting `viewingOrigin` accordingly.
- Modified logic to determine which app version to display in screenshots based on installation status.
- Improved handling of `viewingOrigin` in `AppDetailModal.vue` to default to Spark if no specific version is installed.
