fix(web): clear the saved-badge reset timer on unmount

CI 2891 failed on an unhandled ReferenceError: the 2s
setTimeout(() => setSaveState('idle')) in the settings tabs fired after
jsdom teardown. Replace the three uncleaned timers with one
useSavedBadgeReset effect hook that clears on unmount.

 `next` never publishes npm `latest` or Docker `latest`. The next npm publish step verifies that `@mosaicstack/mosaic@next` resolves to the computed prerelease before the pipeline can pass.
 
+### E2E Gate (#1445, P6)
+
+Trunk publish pipelines run a headless Playwright suite (`e2e` step) before any image publishes: the built gateway `dist` boots on a throwaway embedded PGlite database (isolated via a fresh `HOME`), serves the built SPA bundle through `WEB_DIST_DIR` — the same serving path the gateway image ships — and the suite runs against it inside the pinned `mcr.microsoft.com/playwright` image. `E2E_REQUIRE_SEEDED_AUTH=1` makes login failures hard failures (the skip-when-login-fails guards are a live-environment affordance only). Both image build steps depend on this gate.
