Subject: [PATCH] fix(web): don't use consumer email domains as the company
 domain (#1343)

workspaceDomainFromEmail returned the raw domain for free providers, so a gmail.com user picking Team was shown gmail.com as their company domain. Confirming it named the org "Gmail", persisted brainWorkspaceDomain, and ran company research against Gmail.

It now returns null for consumer providers, so the confirm step starts empty and requires a real company domain.
