Display Aggregate/Summary Widget of Successful Builds

[sophiebr]

- Adds acceptance tests
- Provides configuration option

[sophiebr]

Added a "Collapse Successful Builds" option in the view configuration. When applied, all successful builds are collapsed into a single summary widget.

• If all builds are successful, a full screen summary widget is displayed.
• If not, a summary widget of any succeeding builds is displayed at the bottom of the view. All remaining non-successful builds are displayed in the usual manner.

Acceptance tests also added to make sure this feature works as expected.

Hey @sophiebr, thanks, this looks really cool! I'll review your PR shortly

There are some scaling issues we identified when the collapse option is ticked. I will try to fix that issue. Also, I would like to update the styling so that non-successful badges and the summary badge never "touch."

Currently we're looking for a way to hide successful builds. This looks promising 👍
