[app-attest-env] Merge production-environment fix into opt-in-prompts, port to flat layout

Resolves the App Attest env/entitlements changes onto the flattened
PediFoods.xcodeproj structure (Darwin/PediFoods.xcodeproj no longer
exists on this branch). Also restores Release signing to Manual /
Apple Distribution / AppStore provisioning profile - the merged-in
fix had switched it to Automatic / Apple Development, which breaks
headless CI archiving.
