Give someone access to invoicing

Who: the Owner. Go to: Invoicing → Access.

Pick a Super Admin or Admin (with teams on, a Super Admin: invoicing covers the whole workspace) and what they can do: Make drafts, Issue and share, Record payments, Settings and prices. They're told, accept the invoicing terms themselves before first use, and their issues and payments are recorded under their name. Remove access any time; the invoices they made stay. Employees can't have invoicing. Everyone else sees Invoicing is the Owner's and can ask the Owner for access.
