Bug: Saved Groups Page Crashes with Many Groups (1000+)

[EitanGoldfrad]

The Saved Groups page crashes or becomes unresponsive when there are a large number of saved groups (e.g., 1000+). This issue likely stems from the lack of pagination, which causes all groups to load at once, overwhelming the browser and degrading performance.

Steps to Reproduce
Create or import a large number of saved groups via the API (e.g., 1000+).
Navigate to the Saved Groups page in the Growthbook UI.
Observe the crash or performance issues.

Expected Behavior
The Saved Groups page should load efficiently, regardless of the number of saved groups. Pagination or another optimization mechanism should prevent performance degradation.

Proposed Solution
Implement pagination for the Saved Groups page to limit the number of groups loaded at one time. A reasonable default, such as 20-50 groups per page, could balance usability and performance.
