fix(ui/i18n): unify color themes and complete translations

1. Fix Step 2 UI color theme (changed from Green to Orange to match Home/Stepper).
2. Fix Step 2 layout bug (reduced excessive spacing above marquee).
3. Complete i18n translations for navigation buttons, footers, and marquees across all steps.
4. Add navigation buttons to Step 3 footer.
5. Fix hardcoded text in SimpleHome and Step pages.
6. Adjust spacing in Step 1 and StepProgress for better layout.
