Request password reset email
Send a password reset email via Resend (custom template).
Firebase remains the identity backend (it mints the oobCode embedded in the
link), but the email itself is delivered by Resend — never Firebase's
built-in mailer. Always returns {"status": "ok"} regardless of whether
the email exists to prevent email enumeration attacks.
