Context menu popout & Report definitions Toast fixes

[davidcui1225]

Issue #, if available:
N/A
Description of changes:

• Download in progress modal disappears after any response is received, so it will not remain on-screen after operation is done in error cases
• Commented out report definition toasts since we don't display the report definitions table

Do you confirm that we are not calling the reportDefinition/listAll API when we are on the landing page? (not sure if it's the correct naming, lol)

Yes, I think you are referring to the GET ../api/reporting/reportDefinitions API which is only called once within a helper function refreshReportDefinitionsTableContent that is no longer used anywhere in main
