When a belt drag ends with the cursor over a non-belt building or construction site, the end tile now snaps to the input-capable adjacent tile closest to the cursor and points into the target, instead of showing an invalid ghost on the occupied tile. Adds BuildingSystem::getInputPorts(id) (reusing computeInputPorts, refactored into a bodyCells+outputPorts core) as the single source of truth for a target's input-capable adjacent tiles; works for both operational buildings (stored inputPorts) and construction sites (mask-derived). GameWorldView tracks the cursor world position and, in recomputeBeltDragPath, picks the nearest input port and overrides the end tile's rotation. Ghost preview, resolve, and apply consume the snapped path unchanged. Implements REQ-BLD-BELT-DRAG snapping-to-a-building.
