chore: Remove dead onboarding-flow.tsx and role-card.tsx — no longer imported

[JamesVictor-O]

Problem

Two onboarding components are no longer imported anywhere in the codebase:

• `components/onboarding/onboarding-flow.tsx` — the old modal-based onboarding (replaced by `onboarding-wizard-modal.tsx`)
• `components/onboarding/role-card.tsx` — the old ``-based role card (the wizard modal has inline role buttons now)

Verified via grep — zero imports of either file outside themselves.

---

What to Remove

```
apps/frontend/components/onboarding/onboarding-flow.tsx ← delete
apps/frontend/components/onboarding/role-card.tsx ← delete
```

What to Keep

• `onboarding-wizard-modal.tsx` — the active modal
• `onboarding-modal-context.tsx` — the active context
• `business-form.tsx` / `creator-form.tsx` — used by the modal
• `step-indicator.tsx` — used by the modal
• `stellar-wallet-button.tsx` — standalone component, used in onboarding forms

---

Acceptance Criteria

• Both files deleted
• `npx tsc --noEmit` compiles clean
• `pnpm --filter frontend build` succeeds
• Onboarding wizard modal still functions correctly

Hi maintainers, I can take this if it is still available. I will verify both onboarding files have no imports or dynamic references, delete only those dead files, and run the available frontend type/build checks. I will wait for assignment before opening a PR.

Can I work on this? Kindly assign this issue to me. I would like to clean up the onboarding components by removing the unused files, verifying there are no remaining references, and ensuring the active onboarding wizard flow continues to function correctly. I will also validate the TypeScript build and frontend build requirements before submitting a PR.
