Card image: paste button and site-icon (@favicon) option

The banner panel's card-image block gains a pasteboard button (an image
uploads; an image URL goes as the save message's image setting itself and
is fetched/stored server-side, cross-origin being CORS-blocked for the
browser) and a site-icon button saving the @favicon sentinel, which
resolves to Data.favicon at render time and follows favicon changes.

## Card images
`Node.image` names a content-addressed store file (12-hex hash, served at `/_f/{name}`) used as the page's card image: `og:image`/`twitter:image` meta and the card cover in listings. The effective image follows the priority: the node's own `image`, then one mined from the rendered article (hero → first raster → first SVG), then the inherited image (the nearest ancestor's, the front page last). Set in the editor's banner panel (upload → `PUT /_api/files/{name}`, then a `save` with `image` over the editor WebSocket), stored at `IMAGE_MAXSIZE` like other uploads. `twitter:card` picks `summary_large_image` vs `summary` from the image's probed dimensions (views.py `_image_dims`).
`Node.image` names a content-addressed store file (12-hex hash, served at `/_f/{name}`) used as the page's card image: `og:image`/`twitter:image` meta and the card cover in listings. The effective image follows the priority: the node's own `image`, then one mined from the rendered article (hero → first raster → first SVG), then the inherited image (the nearest ancestor's, the front page last). The special value `@favicon` resolves to the site icon (`Data.favicon`) at render time — it follows favicon changes rather than copying the current icon. Set in the editor's banner panel (upload → `PUT /_api/files/{name}` or paste from the pasteboard — an image uploads, an image URL is sent as the `image` setting itself and fetched/stored server-side by the save handler, since cross-origin URLs are CORS-blocked for the browser — then a `save` with `image` over the editor WebSocket; the site-icon button saves `@favicon`), stored at `IMAGE_MAXSIZE` like other uploads. `twitter:card` picks `summary_large_image` vs `summary` from the image's probed dimensions (views.py `_image_dims`).
`Node.large: bool | None` overrides the automatic card-mode pick per article: None = automatic, False forces a small card, True a large one. Unlike `image`, it is NOT inherited down the tree. Set from the banner panel's card previews (a `save` with `large` over the editor WebSocket).
