💄 style(topup): align container width with PersonalSetting (w-full max-7xl)

- Set TopUp page outer wrapper to "w-full max-w-7xl mx-auto px-2"
  to match PersonalSetting and ensure consistent layout width and padding.
- No functional changes; UI-only adjustment.
- Lint checks passed.
- Verified that pages/TopUp only re-exports the component (no extra wrapper).
