- Adds `blur-xl` class to `SimilarContentCard` thumbnails when blurred, ensuring visual consistency.
- Implements `createModerationOverrideButton`, `createModerationHideButton`, and `createModerationBlockButton` in `SimilarContentCard.js` to provide missing interactivity.
- Updates `VideoModal.js` to wire up moderation callbacks (`onModerationOverride`, `onModerationHide`, `onModerationBlock`) when initializing similar content cards, dispatching global moderation events.
