refactor(web): remove now-unused ViewerAsset proximity $derived

With day-tier boundaries handling viewport classification (previous two
commits), the per-asset #viewportProximity $derived and isInOrNearViewport
getter are no longer read by anyone. Remove them, along with the
calculateViewerAssetViewportProximity helper they used, and the back-pointer
to TimelineDay that only existed to feed the derive.

Net effect at scale: one $derived per ViewerAsset deleted. For a library
with N assets, that's N $derived instances and their dependency-tracking
metadata no longer allocated. The work that those derives did is now
performed lazily, O(log N) per day, by binary search in updateAssetBoundaries.
