Remove hand-written sw.js, offline.html, and manifest.json from todo/skilltree/zitare web apps
in favor of the Workbox-based service worker generated by @vite-pwa/sveltekit. This fixes an
issue where the custom SW could get stuck serving the offline fallback page even when the server
was reachable. Also extracts the duplicated offline page (~80 lines each across 19 apps) into a
shared OfflinePage component in @manacore/shared-ui with 3 props (appName, offlineMessage,
accentColor), reducing each app's offline route to an 8-line wrapper.
