Add two-factor authentication (2FA TOTP) to an existing T3 project's login. Orchestrator - asks which authenticator app the user wants, detects whether the project uses admin auth (single fixed login) or user accounts, and delegates to the right setup. Admin mode - 2FA is mandatory for the single admin, secret + backup codes stored in the Bitwarden vault. User mode - 2FA is optional per user, each user enables it from their account page, secrets + backup codes stored per-user in the database. Requires the project to already have hypervibe auth (/add-auth).
