Standardizes the back button to a single shared component
(AppBackButtonIcon, 32x32/14pt) instead of ~16 hand-duplicated
52x52/24pt copies, and wires each screen through LCENavigationView
per this project's mandatory-usage rule. Home and Store Detail
intentionally excluded - both have bespoke header designs (collapsing
header, hero-image overlay) this change would visually disrupt.
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.
