fix(auth): build verification email URL from ALLOWED_ORIGINS#899
Merged
Conversation
The backend was reading NEXT_PUBLIC_BACKEND_API_BASE — a Next.js browser-bundle env var that isn't reliably injected on the backend container — to construct verification email links. When unset, signups got malformed links like http:///auth/verify-email/<token>/. Switch to FRONTEND_URL (already derived from ALLOWED_ORIGINS at module load) plus the /service prefix that nginx (self-host) and the prod ALB both route to the backend. Same convention as the invite-email link in api/emails.py.
