v0.8.2

Fixed

• Fix UI overlap and scroll bleed on iOS PWA - remove double safe-area padding from body that caused content to shift under status bar (#16)
• Fix page containers using wrong nav height token (56px instead of 68px including dot indicator), causing content to render behind bottom nav on all pages
• Add overflow: hidden to all fixed-height page containers (shopping, meals, notes, budget, contacts) to prevent scroll bleed
• Add overscroll-behavior-y: contain to app-content to prevent rubber-banding scroll propagation
• Fix FAB position on all pages to account for full bottom nav height including dot indicator
• Bump service worker cache version to v23
