LEGEND_APPLICATION_RESET_BACKEND_OVERRIDES_QUERY_PARAM: "resetBackendOverrides" = 'resetBackendOverrides'

Opening the application with this query parameter clears its backend overrides: the way back when an override (e.g. an unreachable SDLC server) keeps the application from loading. A link can clear overrides but never set them: only the user, in the backend servers dialog, sets them.
