refactor: (description) owner command handling && fix colors

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.
