Merged idevice-related commands into a unified GroupCog in cogs/idevice/__init__.py, replacing individual Cog classes with command factory functions. Updated bot.py and help.py to support the new structure and improved command categorization. This refactor simplifies extension loading and command management for idevice troubleshooting features.
