fix(notify): route icon-like content images to the app-icon slot

Clients like kitty, mail and opencode send their icon through the content-image hint, so it drew as a large balloon preview. A theme-name source, an SVG, or a raster small on both sides now fills the app-icon slot instead; a larger raster (a screenshot) stays the preview. An app_icon already present keeps the slot.
