* Rename token -> code

* Add test: don't verify SSO emails through the 6-digits verification

* Add a test on `/user/emails/resend-confirmation-code`

* Rename to `confirmationEmailMiddleware`

* Add `Modules.middleware('confirmationEmailMiddleware')` to `/user/emails/send-confirmation-code`

* Log attempted verifications of SAML emails
