fix(ci view): Setup default theme

Description

• fix(ci view): Setup default theme

On terminals using dark colors on light background, glab ci view was unsuable as "white text on white background" was used, which just showed empty boxes.

Use the trick from https://github.com/rivo/tview/issues/859 and setup a theme, which uses the default colors.
