Mobile view overhaul: bottom nav, card inventory, camera scanner, PWA

Replace the cramped horizontal sidebar with a 5-tab bottom nav (Home, Inventory, Scan, Custody, More) with an elevated scan button. Convert the 10-column inventory table to card-based list on mobile with scrollable filter pills and long-press selection. Add full-screen camera barcode scanner using html5-qrcode with post-scan action sheet. Set up PWA with vite-plugin-pwa for add-to-home-screen. Convert modals to bottom sheets, add pull-to-refresh, safe-area padding, and iOS input zoom fix. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
