High memory usage on authentik client side

[tbbkitty]

Describe the bug
When working for extended periods of time in authentik, added groups making changes etc, the client uses more and more memory. I think it might be a caching issue.

To Reproduce
Steps to reproduce the behavior:

1. Create groups in authentik UI
2. Add users to groups
3. Observe console log for high memory usage. Not going down until tab is terminated.

Expected behavior
Cache to be flushed once content is no longer needed.

• authentik version: 2025.4.0
