Runs the detail page through the service worker's real network-first API
strategy against an in-memory cache: a visited grounded dinner reloaded
offline shows its photo, ingredients and steps with the offline indicator
(phone and Kitchen reading mode); a dinner never visited shows the error
with Retry; a saved pending copy stays "still finding the recipe".
Moves the worker test harness out of apiStrategy.test.ts into
src/test/serviceWorker.ts so both tests share it, and routes network-only
paths (settings) straight to the network as the worker does.
No product change: the existing route, strategy, apiRead and page already
satisfy the done-condition.
