Fix #511

[augmentcode]

🤖 Augment PR Summary

Summary: Fixes SafeAreaPaddingModifier so it no longer introduces unintended extra spacing and respects the requested edge set.

Changes: Re-enables the previously disabled UI snapshot test for #511, sets safeAreaInset spacing to 0, and ensures insets are applied only for edges included in the modifier’s edges set.
