When DISABLE_REGISTRATION=true (or 1), POST /api/auth/register returns
403 with a clear error. OAuth endpoints (/google, /microsoft) also
refuse to auto-create new accounts — existing OAuth users can still
sign in. First-user setup (empty users table) is always allowed so a
fresh install can still be initialized.
GET /api/auth/config now returns registration_enabled so the login
view can hide the "Create Account" button and the trial banner when
registration is off. Absence of the flag is treated as enabled for
back-compat with older servers.
