PULL REQUEST

Summary

Followup to the fixes to the other PR that went in that

Changes the default medication admin request to be more in line with what was intended (thanks Marcelle!)
Fixed the copy for the redirect toast between customize query --> select query
Standardizes the spacing within and between page grouped page elements (to 12px / 40px respectively, as defined in their variables within _variables.scss)
Defines some site-wide width defaults (main-container and main-container__wide) for the types of pages we have based on a convo with Michelle (ie the classes in layouts.scss that we're deriving from some tokenized width values)
Added some code in the ResultsView that will filter out columns for display if there's nothing to display
Moves the page files into the folders that are there to make them easier to find
Some styling quality of life cleanup / definition

Got an OK from Michelle synchronously
