Add internal staff IAM: named users, roles, and management permissions.

verae-staff-iam (:3028) is the people directory — owner, billing-admin,
cs, sales, accounting, operator, viewer — with scrypt passwords, sessions,
and an audit log. Admin console login uses it when STAFF_IAM_URL is set
and hides tabs the account cannot use. CS/sales/accounting/staff/fleet
check permissions such as cs.credit and fleet.operate. Shared staff key
remains only as a fallback when IAM is unset.
