[BUG] Very poor downloads tab performance with a large number of tracks

[ArtikusHG]

Describe the bug

I have about 600+ tracks downloaded. When I open the downloaded tab, it lags for ~30 seconds, then works fine, but occasionally my phone shows "tempo is not responding" messages. Deleting a track takes like 2 minutes because of the lag.

Expected behavior

The lag shouldn't happen. Other parts of the app work fine.

To Reproduce

1. Download a lot of tracks
2. Go to downloads tab
3. (Optional) Try deleting a track

Environment

• Android device: Google Pixel 6 Pro
• Android OS version: 15
• App version: 3.9.0
• Other relevant details: Using Navidrome if that helps
