ServerLogTask now embeds the full config in its JSON output, matching SudLogTask — so replay_sim and analyze_log work on server logs without needing a separate config file. replay_sim.py switches from two positional args (date_time, sud_name) to a single log file path, with config and plant params resolved from the log's embedded "Config"/"PlantParams" sections when present and falling back to config.json / hardcoded defaults for older logs.
