LP1883171 & LP1940663: Update Staff client changes based on feedback

Modify the Item Staus view to check the new return values of the
update copy inventory function.

Fix toast handling in the list view to properly report success and failure.

Add toast handling to the single copy Item Status view to report
success and failure.

NOTE: More work could be done on the toasts to report number of
successful updates, etc.  I tried using the compileContent and trusted
HTML, but this lead to new errors that I couldn't decipher.
