fix(dashboard): keep unverified users on enroll page after join

After email login, auto-enroll was redirecting to /lms or the admin
/courses/:id/lessons route. Unverified users cannot use the LMS yet
(VerifyEmailModal on app routes), which felt like a permission error.

Enroll without verification, but stay on the enroll page with a verify
prompt instead of redirecting until email is confirmed. Also fix custom
domain org lookup to use hostname without backend port.
