Error Modal: Order has inactive Vendor/Access Provider

Purpose: To keep users from ordering from inappropriate Vendors

-Scenario 1
Given that I am creating or editing an order
When I use select a Vendor
Then the system will only display "active" Vendors-

Scenario 2 (moved to a separate ticket UIOR-193)
Given I have a pending order
When opening the order
Then the system must check and validate that the vendor is Active
IF Vendor is inactive
Then the system should display a modal "This order cannot be open as the associated Vendor is Inactive"
Then user must click "continue" to cancel operation and continue editing.

Scenario 3
Given The "Access provider" of the E-resource Details of the PO Line is inactive or no longer exists
When opening/updating the order
Then a modal should display with PO Line number(s) and message reads "POL# is using an Access Provider that is inactive or has been removed, please select an active Access Provider to continue."
