chore(ai): format sources and fix moderation bugs (agent)

- Format `css/tailwind.source.css` with Prettier.
- Add allowlist entry for `VideoCard.js` media query pixel value in `scripts/check-design-tokens.mjs`.
- Remove accidental artifact `js/ui/dm/jules_session_4520373547615093905.zip`.
- Fix bug in `js/app.js` and `js/services/moderationActionController.js` where blocked users' videos were not correctly hidden in the UI immediately after blocking.
- Fix bug in `tests/app/moderation-overrides.test.mjs` where `userBlocks` mocks were insufficient to reflect state changes.
