- Ebike replacement parts: cooling core (correct, anchored at refroidisseur)
+ four distractors anchored at cabledroit/cablegauche/pucehaut/pucebas.
Removes the ad-hoc gant_l/talkie distractors in favor of consistent
case-anchored visuals.
- Pylon replacement parts: cable1 + cable2 (alternative correct, both with
caseLockGroup 'pylon-cable' for upcoming soft-lock) + refroidisseur and
two puce distractors anchored to packderelance.
- Farm replacement parts kept as-is (caseAnchor undefined falls back to
placeholder slot positions for backward compatibility).
- RepairGame threads anchors from RepairCaseModel through RepairMissionCase
to RepairRepairingStep; replacement-part initial position now resolves
to the anchor world position when caseAnchor is set, falling back to the
legacy slot index otherwise.
