Add interactive-only server edit command

- Add new mcpm edit command for interactive server configuration editing
- Support STDIO servers (command, args, env) and remote servers (URL, headers)
- Interactive form-based editing with InquirerPy for better UX
- Real-time validation and confirmation before applying changes
- Graceful fallback with clear messaging in non-terminal environments
- Comprehensive test suite with proper error handling
- Clean, single-file implementation for maintainability
