Improve pipeline status icon linking in widgets

What does this MR do?

• It improves the linking of the status icon to be consistent with other status icon linking usage throughout the application
• it replaced the overal pipeline status icon in the pipeline view widget, as its duplication of content

Are there points in the code the reviewer needs to double check?

• In the commit view widget, I would like the linking to be directly to the pipeline, instead of opening the pipelines tab in the commit view...
• in the mr view widget, there seems to be a hover underline style acting up or something (see gif screenshot)

Why was this MR needed?

• consistency
• duplication of content
