refactor: extract authentication system to auth package
- Create auth/jwt.go with JWT token management - Create auth/permissions.go with permission checking logic - Create auth/storage.go with storage key utilities - Create auth/auth.go with main authentication service - Create auth/middleware.go with auth and rate limit middleware - Update main.go to import auth package and use auth.* functions - Add authService to Server struct Major auth functionality now separated into dedicated package. Build tested and verified working. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
