Manage AI features by user (personal user settings)

We would like to be able to disable certain AI features on a per-user basis without changing the global permission group. Currently, when we manage AI settings, they are applied to all users at the account level.

To disable AI usage for some team members, we have to modify their permission group. However, this affects a significant number of users in our organization: we would need to duplicate existing permission groups just to remove these usage settings for a few team members.

It would therefore be beneficial to allow these settings to be modified or to disable AI individually for certain users, as we can already do for notification preferences.
