- Replaced imports in VerifyEmailPage.tsx (verifyEmail, resendVerificationEmail → authApi.verifyEmail, authApi.resendVerification)
- Replaced imports in useUsernameAvailability.ts (checkUsernameAvailability → authApi.checkUsername with response.available extraction)
- Replaced imports in usePasswordReset.ts (requestPasswordReset, resetPassword → authApi.requestPasswordReset, authApi.resetPassword)
- Replaced imports in RegisterPage.tsx (resendVerificationEmail → authApi.resendVerification)
- All function calls updated to use authApi methods with proper request object wrapping
- Test files still use direct imports (acceptable - tests can use implementation details)
- AuthContext.tsx uses services/authService (legacy service, separate from features/auth/services/authService)
- No TypeScript errors related to authApi
- Action 6.1.1.8 complete
