The bug: Junctions lose their socket-to-pole mapping on save/load because
FCrLogisticsSocketsFragment isn't savable. All drones collapse to the center lane.
2
The fix: Rewrites spline endpoints so each lane connects through a dedicated
invisible pole instead of sharing the junction entity. The game's loader can't collapse them.

Safe: Creates a backup, removes stale poles and drones (they respawn), and
everything runs in your browser — your save file is never uploaded anywhere.
