Refactored embed creation and sending in moderation warnings and owner cog management for consistency and improved user feedback. Added author and title fields to embeds, centralized embed sending logic, and enhanced error reporting with exception details. Moved NotOwner error handling from bot.py to cog_management.py for owner commands.
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.
