style(install-banner): match font sizes to resource items

Change install banner text sizing to match OpenShift-style resource items:

- Title: 16px (matches .resource-name)

- Subtitle: 14px IBM VGA 8x14 (matches .resource-cmd)

- iOS instructions: 14px IBM VGA 8x14 for consistency

Removes experimental pixel art wizard character.
