refactor(sidestore): commands into single GroupCog

Converted individual sidestore command cogs into functions and grouped them under a new Sidestore GroupCog in cogs/sidestore/__init__.py. Updated bot.py and help.py to recognize the new 'sidestore' category. This simplifies command registration and improves maintainability.
