fix(details): improve coroutine management and cleanup profile UI

This commit addresses potential memory leaks and state inconsistencies in `DetailsViewModel` by refining job management and simplifies the `ProfileRoot` UI by removing the redundant back navigation button.

- **fix(details)**: Updated `InstallWithExternalApp` logic to correctly handle `CancellationException`, resetting the UI state and clearing asset references when a job is cancelled.
- **fix(details)**: Improved `currentDownloadJob` lifecycle management using `invokeOnCompletion` to prevent race conditions when multiple jobs are launched.
- **refactor(profile)**: Removed the manual navigation icon from `TopAppBar` in `ProfileRoot.kt` and cleaned up associated imports.
