Summary

• Corrects the isDisposableEmail TSDoc: quickValidateEmail's short list is not only client feedback — it also runs server-side (email OTP sending, organization invitations, invoice notifications, contact/demo contracts). The real reason it stays a separate short list is that it runs in browser forms, where the full list cannot ship
• This PR originally carried follow-up polish to fix(auth): refuse account creation from disposable email domains for every provider #9516; fix(auth): block only curated disposable domains, and never gate SSO or SCIM provisioning #9529 (merged since) supersedes all of it — curated list with public suffixes filtered, emailDomain normalization, SCIM/SSO exemption in disposable-email-gate.ts, the signup-form message, and the real-betterAuth gate tests — so the branch was reset onto staging and only this correction remains
