Total losses and adjustments modal/cell needs disabled state

Currently if a product line item is skipped, or a requisition is in the Authorized state, changes can sill be made to the total losses and adjustment modal.

In the disabled state the losses and adjustment cell should not show the edit pencil, but rather an external-link icon — and the edit pencil should be changed to the pencil-box icon to preserve consistency

In the disabled state the modal should only display a list of losses and adjustments, the addable form should be removed, and the text fields and 'remove' button should be hidden — leaving only the value and type visible (bonus points for displaying this in a `<dl>` list

Acceptance Criteria

• When requisition is in 'APPROVED' or 'AUTHORIZED' state, total losses and adjustment cell and modal are not editable (in a disabled state)
