I've identified several issues with the current protobuf files that need to be addressed:

• Missing Message Definition: In the braking_service.proto file, there is a BrakeAssistance publish topic, but the corresponding message definition is missing in its topics proto.
• Incorrect Resource name: In engine_service.proto, the publish topic is defined as:
  option (uprotocol.publish_topic) = { id : 0x8001, name : "horn", message : "oil" };
  This should be updated to:
  option (uprotocol.publish_topic) = { id : 0x8001, name : "oil", message : "Oil" };
