fix(telemetry): populate missing fields in node execution trace

- Extract model_provider/model_name from process_data (LLM nodes store
  model info there, not in execution_metadata)
- Add invoke_from to node execution trace metadata dict
- Add credential_id to node execution trace metadata dict
- Add conversation_id to metadata after message_id lookup
- Add tool_name to tool_info dict in tool node
