fix(cirkel): cover videos are decorative — no <video> right-click menu/controls
A cover that federated as an MP4 renders as a real <video>, so right-click
showed the browser's video menu (Loop, Show all controls, Picture in
picture, Save video as) and clicks hit the video instead of the tile link.
pointer-events:none lets clicks + right-click fall through to the tile <a>
(normal link menu, whole tile clickable); autoplay is unaffected.
- src/assets/css/style.css — pointer-events:none on cover videos (grid/list/post)
- src/views/shell.ejs — style.css buster v66 -> v67
