[BUG] Notify the user when out of space while attempting to install an app

### Guidelines

- [x] I have searched the issue tracker for [open](https://github.com/Droid-ify/client/issues) and [closed](https://github.com/Droid-ify/client/issues?q=is%3Aissue+is%3Aclosed) issues that are related to the bug report I want to file, without success.
- [x] I'm on the [latest](https://github.com/Droid-ify/client/releases/latest) released version.

### What happened

I ran into an issue recently where my phone had enough storage space to download an APK, but not to install it. When this is the case, the behaviour from Droidify is confusing -- it downloads the app successfully, prompts for installation, and then the installation silently fails with no feedback. If a notification popped up that the user is out of space here, that'd be handy!

Thanks for Droidify :-)

### Additional context

_No response_

No files, tests, or entry points are named. Start by reproducing the failed installation on a Pixel 4a running GrapheneOS 13, then trace the installation flow and identify how an out-of-space failure is reported; done means the user receives a clear notification when installation cannot proceed because storage is insufficient.
