[$40] Make toastr messages always visible #95
Description
Follow up issue from #82 (comment) issue 6:
the red toastr message is not visible if the resources per page is more and the modal also is still opened which is causing confusion.
When the page has a scrollbar and we make some operations at the bottom of the page we don't see the toastr which migh lea to confusion. For example when we perform some operations like editing payment or adding additional payment and it fails, the modal would stay open but we would not know that some issue happened.
To fix it we have to make sure that toastr is always visible even if scroll down.
The perfect solution if toastr message would be sticky see demo https://react-sticky.netlify.app/#/basic (this library seems to be maintained, but maybe there is a better one which is maintained https://www.npmjs.com/package/react-sticky-el)
