Lf 4948 snackbar should be full width and centered on mobile

[Duncan-Brain]

Description

This fixes the main centering and incorrect width issues with the snackbar.

Notes:

• malayalam sets the global variables in the side menu and is its own special case
• on mobile technically either isCompact and isExpanded could be true and so expanded as default with an override pattern was expanded upon

Scrollbar:
Pre-existing but the scrollbar creates a noticeable difference in centering in some screen sizes. For top level centering like tasks and crop catalogue this centering could be fairly easily solved. But for screens like animals and inventory where the table holds the scrollbar it is not as easy. Let me know if there is interest in the top level centering here but it seems like we are maybe moving more towards the table views.

Fix for mobile looks good and the re-org of selectors makes sense to me!

There are just two small introduced bugs that are detailed in-line below. One is the Malayalam width override has been lost, and the other is that snackbar width is no longer responsive to the compact side menu state

Just a few selector issues contributing to that, mentioned below. Rest LGTM!
