Sync macOS Brave wallpapers to iOS (with optional iOS upload for mobile-only users)

Hi Team, my main request is not necessarily to add a full wallpaper upload on iOS, but to improve wallpaper consistency across devices.

Ideally a custom wallpaper set on Brave for macOS should automatically sync and be applied on iOS via Brave Sync. This would ensure a consistent experience.

For comparison, Safari already syncs custom backgrounds from macOS to iOS, which creates a seamless transition between devices.

At the same time, I think it would be worth considering an optional solution for users who only use Brave on iOS and don’t own a Mac or desktop device.

Currently, the lack of wallpaper syncing is one of the few remaining reasons holding me back from fully switching from Safari to Brave across all devices.

Thanks for considering it.
