Case Study bug: remove "CUSTOMER STORIES" badge and side bar content getting cut off.

[linear[bot]]

These fixes should apply to all customer stories using the new template:

• [ ] The badge at the top of the page shouldn't be there. Please remove the "CUSTOMER STORIES" badge entirely, and just leave the back button. I'd also rename the back button from "BACK TO RESOURCES" to "Customer stories".

• [ ] The content on all sidebars that is meant to be sticky on scroll is getting cut off. Can we adjust that spacing so the full content stays visible on scroll? See screen shots.
