Describe the bug
When downloading a VM, the app displays "Waiting for download to start", with an infinitely sliding progress bar. No progress is shown. It remains in this state until the download eventually completes.

To Reproduce
Steps to reproduce the behavior:

1. Open app
2. Click "Create new machine"
3. Choose any OS and any version
4. Click "Download"
5. Observe app

Expected behavior
When downloading a VM, the app should indicate that the download is in progress with text such as "Downloading..." or "Download in progress...", and ideally the progress bar should actually show the progress, or at the very least a percentage should be displayed.

Desktop (please complete the following information):

• Quickgui Versdion: 1.2.8-1
• Quickemu version: 4.9.5
• OS: NixOS
• Version: 24.11 (latest unstable)

Please update quickgui. Quickgui 1.2.8 does not support the progress indicator of curl that quickget now uses. Fixed in #138
