fix: center and resize file chooser,save,download dialogs in Hyprland (#1216)

### Summary
This PR fixes an issue where file chooser dialogs (Open, Save, Upload)
were spawning partially off-screen in Hyprland.
The root cause was case-sensitive mismatches with
`Xdg-desktop-portal-gtk` and missing explicit window rules.

### Changes
- Added `windowrulev2` rules to ensure:
  - File chooser dialogs float
  - Open centered on screen
  - Use consistent 70% sizing relative to monitor

### Testing
- Verified in Hyprland on Arch Linux
- Tested with Brave, Firefox, and system upload/save dialogs
- All dialogs now correctly center instead of opening off-screen

### Changelog
#### Fixed
- File chooser dialogs in Hyprland now open centered and floating
instead of off-screen
