Investigate login verification loop issue

[mfts]

Normalize URL origins in isValidVerificationUrl to fix a login verification loop.

The previous comparison urlObj.origin !== process.env.NEXTAUTH_URL failed when process.env.NEXTAUTH_URL included a trailing slash, as urlObj.origin never has one. This mismatch caused the verification to fail and users to get stuck in a login loop. The fix ensures both URLs are normalized to their origin before comparison.
