fix: Snackbar messages are not bottom centered during standups

[gitstart]

Description

Fixes/Partially Fixes issue

After digging, I discovered that the snackbar was positioned relative to the sidebar on the left, so this affected the positioning on pages that the sidebar isn't in view.

I modified the code to add the width of the sidebar to the position of the snackbar only when the screen is desktop when the page is not a meeting i.e when the sidebar is showing.
