Moves the moderation warning badge ("Content blocked...") to overlay the blurred thumbnail image instead of sitting below it or increasing card height. This logic is applied to both the main `VideoCard` and the `SimilarContentCard` to ensure layout consistency.
Changes:
- VideoCard.js: Refactor `updateModerationBadge` to append the badge container as a child of the `anchorEl` (thumbnail wrapper) with absolute positioning.
- SimilarContentCard.js: Implement `refreshModerationUi` logic to generate and overlay a simplified moderation badge on the thumbnail when `trustedMuted` context is present.
- Fix tests/moderation/video-card.test.mjs: Patch test environment to mock `globalThis.navigator`.
- Remove view count and separator from the metadata row in `SimilarContentCard.js`.
- Add new `buildEngagementSection` method to render view count and discussion count in a dedicated footer.
- Use Eye and Message SVG icons for engagement metrics.
- Ensure visual consistency with the main Video Card component.
- Fix import and definition of `SVG_NAMESPACE` to support icon creation.
- Refactored `SimilarContentCard.js` to use Flexbox layout.
- Updated `css/tailwind.source.css` to remove grid layout and use standard flex utilities.
- Improved thumbnail sizing (16:9, fixed width) and responsiveness.
- Added hover effects (background color, thumbnail zoom).
- Cleaned up typography and metadata hierarchy.
