fix: Adapt control units to new entity container

• PathControlUnit: copy orientation from entity to entity container if it isn't changed by path control unit to account for modifications from outside
• Lane offset control unit: re-init offset spline if position or orientation was modified from outside
• entity container:
  • check for changes from outside not only for position but also orientation
  • delete unused members
• abstract control unit:
  • check for orientation changes as well
