Makes job log viewers color palettes consistent

What does this MR do and why?

This change makes the colors of the job details page and the job log viewer consistent.

When we initially developed the full log viewer we didn't care to make ti look exactly like our current logs, now that it has matured, we can try to match the colors and use an SSOT for them.

Changelog: changed

Note: This MR depends on !161461 (merged)
