refactor(ui): clean up stepper and standardize margin spacing

- replace uni-icons with van-icon in Stepper component
- fix semantic markup by replacing <text> tag with <span> in Stepper
- inline SCSS styles for Stepper and remove unused image and style files
- standardize ml-4 utility class to ml-[4px] across multiple UI components for consistent exact 4px horizontal margins
