Greptile Summary

Fixed EMAIL_NOT_VERIFIED error handling in login form by adding proper redirect logic to the onError callback. Previously, when this error occurred, the callback would only set errorHandled = true without actually redirecting the user to the verification page, leaving users stuck on the login screen.

• Added sessionStorage.setItem('verificationEmail', email) to store the email for the verification page
• Added router.push('/verify') to redirect users to email verification
• Removed misleading comment claiming the catch block handles this case (the onError callback executes first, preventing the catch block from running)
• Matches the existing pattern used in the signup form at apps/sim/app/(auth)/signup/signup-form.tsx:330
• The catch block at line 288 still provides fallback handling for edge cases where the error might not be caught by the onError callback

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is a straightforward bug fix that adds the missing redirect logic for unverified email errors. The implementation follows the existing pattern used in the signup form, uses proper SSR checks (typeof window !== 'undefined'), and correctly sets the email in sessionStorage before redirecting. The fallback catch block at line 288 remains in place for redundancy.
• No files require special attention
