[cms] Cannot audit line items of type Expense

[xaur]

I see only Labor line items for same-domain invoices, but not Expense. I think it is reasonable to allow domain peers to audit expenses to make sure nobody buys an overpriced event ticket, pays a crazy service fee, etc.

While I somewhat agree, this needs to be discussed further. Maybe @behindtext has some input into this restriction.
