Map contact persons to registered users via contact.role_id

contact.role_id stores the user_id of the linked registered user (NULL = no
account). load() joins users_users on role_id to expose linked_user_login and
linked_user_name. verify() accepts user_id from the edit form and writes it to
contact_store['role_id']. getList() now filters by user_id key (was role_id).
Edit form shows the user_id field to admins with current login shown inline;
display template shows the linked user when set.
