Pull Request Overview

This PR reintroduces collapse/expand functionality for collections in the data modeling diagram view, controlled by a new feature flag enableDataModelingCollapse. By default, all collections are expanded, and the collapse functionality is only available when the feature flag is enabled.

• Adds a new isExpanded boolean property to collection data models with a default value of true
• Introduces a feature flag enableDataModelingCollapse to control the visibility of collapse/expand functionality
• Implements a ToggleExpandCollection edit action to handle expand/collapse state changes

Not sure if it needs a separate controlled rollout flag in atlas, but if you feel like setting one up it doesn't hurt 🙂

Yeah I'm also not sure. Actually, let's remove it, we can add if needed, but otherwise it'd just complicate the release
