feat: display cross-version installation status in app detail modal

- Replaced single `currentAppIsInstalled` boolean with `currentAppSparkInstalled` and `currentAppApmInstalled` in global store.
- Updated `checkAppInstalled` logic in `App.vue` to fetch the installation status for both Spark and APM versions via `ipcRenderer`.
- Passed both flags to `AppDetailModal.vue` as props.
- Enhanced `AppDetailModal.vue` to compute the "install" button text dynamically: if viewing Spark and APM is installed, it displays `（已安装apm版）`; if viewing APM and Spark is installed, it displays `（已安装spark版）`. The button is also disabled in these scenarios to prevent duplicate cross-version installations.
