Adds /invoices/upload-receipts as the dedicated explainer for the mobile scanner PWA: install instructions for iOS/Android, direct deep-link button, and a walkthrough of the scan -> verify -> save flow. Sidebar entry replaces the old "Scan receipt" tab so the desktop side picks up the install steps before sending users to the mobile-only surface. Scanner layout moves PWA manifest + apple-* meta tags from inline JSX into Next.js's metadata/viewport exports so the App Router doesn't try to render a second <head>, fixing a hydration error that surfaced as two console warnings on the scan page. Scanner shell gains a centered Port Nimara logo header so the standalone PWA looks branded when launched from the home screen without the dashboard chrome.
