refactor: adopt text-ink-600 token and clean up OrderCard

Replace all hardcoded #525866 text color with the text-ink-600 design token across components and pages. Refactor the OrderCard component by moving external SCSS styles to scoped styles, replace legacy class names with Tailwind utilities, and fix minor inconsistencies. Fix the typo in src/pages/quick/index.vue where rounded-[5px]0 was used incorrectly, and delete the unused OrderCard styles file.
