Create or replace a seven-day, email-bound owner invitation; does not send messages

Returns a secret once. Replacement revokes all older unused owner links. The recipient must verify the invited email and use a fresh email-code session. Business phone is contact-only. Accepting activates the workspace atomically; historical phone-bound invitations require reissue.
