feat(fc2a): add ImageCanvas (pan/zoom) and VideoCanvas (with format gate)

ImageCanvas mounts an <img> wrapped in the usePanZoom composable — spreading its handlers onto the container element. Zoom resets when src changes so prev/next nav doesn't carry zoom state into the next image. VideoCanvas plays MP4/WebM/Ogg/MOV natively. Non-playable formats render a friendly explainer with a download fallback, naming the actual MIME so operators know what they're dealing with, and pointing forward at FC-2e where transcoding lands.
