Converted individual moderation command cogs (ban, kick, purge, warnings, archive, hackban, nick) into command factory functions and registered them under a new Moderation GroupCog in cogs/moderation/__init__.py. Updated bot.py and help.py to support the new moderation group and category. This improves organization and enables grouped moderation commands.
Introduces a new 'translate' command under a utilities category, with language autocomplete and Google Translate integration. Updates README and help command to reflect the new category and command. Renames 'rr.py' to 'rickroll.py'. Updates moderation cogs to use a new icon URL for embed authors.
Removed template copyright headers from moderation cogs and database files. Improved embed styling and consistency in purge and warnings commands, including unified colors, author fields, and permission checks. Added a helper for sending embeds in warnings cog and replaced decorator-based permission checks with manual checks for better feedback. Updated comments in database files.
