Adds a "Save offline" button on the recipe page that force-refetches the current page so the service worker's cache picks up a fresh copy right now, plus a small IndexedDB-backed list (lib/offline-db.ts) of what's been saved. The /offline fallback page now reads that list and renders it instead of being a dead end with just a "go back" link. Also fixes the service worker's network-first fetch handler, which never wrote successful responses into its cache -- meaning the existing offline page's claim that "recently visited recipes are available" was never actually true. It populates the cache on every successful GET now. Background sync: marking a batch-cook dish as cooked while offline (the only existing mark-cooked call site in the app) now queues the request in IndexedDB instead of just failing, and registers a Background Sync (public/sw.js's "sync" listener replays the queue) for Chromium; lib/offline-queue.ts's online-event fallback covers Safari/Firefox, which never fire that event at all. Both replay paths read/write the same IndexedDB store so either one drains it. Also removes apps/web/public/manifest.json, a stale static manifest that layout.tsx used to link to before the previous commit pointed it at the real generated route (app/manifest.ts) -- it had gone unnoticed and unused since.
