feat(dl): enhance episode folder structure and rename series folders

- Create nested folder structure for episodes: {title}/Season {season:02}/{filename}
- Keep existing folder naming for songs unchanged
- Modify episode folder naming to only show title for main folder
- Adjust episode file naming format to include separators and sanitization
- Add get_season_folder() method returning 'Season XX' for episodes
- Disable series year inclusion in folder and episode naming by default in config
- Comment out additional service and audio language tags in episode naming code
