[WIP] Use GeometryReader instead of pulling UIApplication.shared.connectedScenes

[Camji55]

Potential fix for #2495

Test

Started with next-dev branch, commit 16aa5b1

Since I am also testing Xcode 27 beta 5, I needed to make some updates in addition to the Loop change, and I'm doing some OmnipodKit testing at the same time.

• Loop to this PR (32c7ff8)
• LoopKit to tip of next-dev (Xcode 27)
• TrueTime.swift to tip of master (Xcode 27)
• OmnipodKit to fix/inplay-eager-connect-watchdog

Build with Xcode 27 beta 5 onto iPhone SE 3rd generation running iOS 26.6

Since we don't know how to reproduce the error, can't tell if this fixes anything. But I am getting these messages in Xcode:

Invalid sheet detent height: 0.0

I rebuilt with Loop next-dev branch and still see the error messages in debug log, so that is not related to this code change

Hi @Camji55,

I'd be happy to test this PR.

Unfortunately, I don't know how to build directly from this pull request. The issue is still occurring for me almost daily, so I should be able to provide useful feedback.

Could you please explain how I can build and test this PR from my existing next-dev setup?

Since the problem is easy to reproduce on my device, I'd be glad to verify whether this change resolves it.

Thanks!
