Second pass integration of Patterfly's dark mode

As a developer, I want to be able to fix remaining issues from the spreadsheet of issues generated after the initial pass and spike of adding dark theme to the console.. As such, I need to make sure to either complete all remaining issues for the spreadsheet, or, create a bug or future story for any remaining issues in these two documents.
