Expand loop translations and rename max_history

Replace the single "loop" translation with three explicit keys ("loopOff", "loopTrack", "loopQueue") across all language files to support distinct loop modes. Also standardize the settings key from "max-history" to "max_history" and update main.py to read LOG_SETTINGS.get("max_history", 30) for the TimedRotatingFileHandler backupCount. Files changed: langs/*.json, main.py, settings Example.json.
