Standardized embed colors to Discord blurple (0x7289DA) across all cogs. Refactored owner command modules (say, shutdown, sync) to use a shared send_embed helper and improved error handling for permission checks. Updated botinfo title and improved bot owner/team logging in bot.py. Help command now always lists 'owner' category, removing permission checks from category display.
Deleted the unused template testcommand cog and removed references to it in help.py. Updated copyright headers in database files to reflect usage and edits by neoarz. Also removed copyright and description headers from several Python files for consistency.
