[Bug] Signup route calls referral helpers that are never imported

[RUKAYAT-CODER]

Overview

src/app/api/auth/signup/route.ts calls validateReferralCode(), referralCodeExists(), and getReferralCodeOwner() but none of these functions appear in the file's import statements. Node.js throws ReferenceError at the point these are invoked, breaking signup for any user who provides a referral code.

Specifications

Features:

• Referral code validation works end-to-end without runtime errors

Tasks:

• Add import { validateReferralCode, referralCodeExists, getReferralCodeOwner } from '@/lib/referral' to the route file
• Verify each imported function exists and is exported from src/lib/referral.ts
• Add a test covering the full signup path when a valid referral code is provided

Impacted Files:

• src/app/api/auth/signup/route.ts
• src/lib/referral.ts

Acceptance Criteria

• Signup with a referral code completes without a ReferenceError
• All three referral helpers are imported and resolve correctly
• TypeScript compilation succeeds with no missing-module errors

Hello,

I'd like to work on this issue. I can fix the missing referral helper imports in the signup route, verify the helpers are correctly exported from the referral module, and add test coverage for the referral signup flow to ensure it completes successfully without runtime errors or TypeScript import issues.
