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.
Introduces a new 'refresh' command for troubleshooting app refresh/install issues. Updates 'Edit Command' button URLs in code, pairing, server, and sparse cogs to point directly to their respective source files on GitHub. Removes timestamp from server cog footer.
