Center info page

[thebagmaster]

The design file was updated to show the cover for the onboarding prompt was changed to be centered. This required some cleanup in both in InformationPage as well as OnboardingCover. This small change should help with future usages of InformationPage.

The changes include:

• ~Removing states from InformationPage in favor of local bool~ Just some edits to the changes for the states
• Adding an encompassing ColumnLayout as well as a ~filler item~ < Bad practice
• Moving control for centering into OnboardingCover

edit: see comments below for working screenshots.

Rebased 27381c0 Added the states back in Had to respect button position for desktop should behave like design doc again Also used isMobile instead of an inline test

Closing for now; this needs to be rebased over main, but we'll be taking a different approach as to the view components and how we handle desktop vs mobile
