In the JSDOM environment, `requestIdleCallback` was missing, causing a fallback to `setTimeout`, which introduced asynchronous behavior that the existing tests did not account for. This change adds a synchronous polyfill for `requestIdleCallback` in `tests/test-helpers/setup-localstorage.mjs`, ensuring that deferred writes happen immediately during testing, restoring deterministic behavior.

Updating `js/ui/components/VideoCard.js` to use `display: flex !important` instead of `block` for the hidden summary container, ensuring consistency with `bv-stack` class and preventing layout issues that made the button unclickable. 2. Adding `url` to fixture videos in `docs/moderation/fixtures/index.html` to prevent them from being hidden by source visibility logic. 3. Adding `onModerationHide` handler to the fixture factory to support the "Restore default moderation" action. 4. Uncommenting the test case logic in `tests/visual/moderation.spec.ts`.

This caused the moderation visual test fixtures, which used dummy data without sources, to be hidden (`hidden=""` on root element) in the DOM, even though they were "visible" in terms of layout (display: block forced on inner container). This state prevented Playwright from interacting with the "Show anyway" button, causing click timeouts. This change: 1. Updates `docs/moderation/fixtures/index.html` to provide a dummy URL for all fixture videos, ensuring the card remains visible and interactive. 2. Implements the missing `onModerationHide` handler in the fixture logic to support the full override/restore lifecycle in tests. 3. Uncomments and restores the failing assertions in `tests/visual/moderation.spec.ts`. 4. Removes `force: true` from click actions as the elements are now properly visible.
