Warning "No collider found" when placing a reversed track buffer (RailBlock)

Issue description

Log message:

W ~Mai: No collider found for layout entity 'TrackBufferReversedStraight0_R0_G0' (prefab: 'Assets/Base/Trains/RailBlock.prefab').
  at Mafi.Unity.Entities.Static.LayoutEntityModelFactory.Create (ILayoutEntityProto proto)
  at Mafi.Unity.Trains.TrainTrackEntityModelFactory.create (IEntityWithTrainTrackBaseProto proto, Boolean isPreview, Boolean skipCollider, Single maxDistanceUnity)
  at Mafi.Unity.Trains.TrainTrackEntityModelFactory.Create (IEntityWithTrainTrackBaseProto proto)
  at Mafi.Unity.Entities.ProtoModelFactory.CreateModelFor[TProto] (TProto proto)

Impact: No crash. The buffer only gets the generic box collider, so picking/hover may not match the model exactly. It also adds a warning to every log.

Reproduction steps

1. Start or load a save without mods.
2. Build a straight train track.
3. Place a track buffer (bumper) on the track.
4. The warning appears in the log.
