Fixed some errors in functions

There were a bunch of quotes missing from some of the
`navigate_to_screen` functions, as well as some instances of using
`create_if_nonexistant` when we changed it to
`create_panel_if_nonexistent`.
Added SNAP approvals

Used @robertfewins-kalb's approver, but added a blip about FSET
orientation.
Modified MAXIS_background_check, now it is more functional

Added blip about navigating to STAT/SUMM, as before it was uncool-ly
sitting there waiting for a case to get out of background (without
navigating to an actual MAXIS screen to do the checking).
Added WREG to my two scenarios
