Fix Grant All checkbox not showing indeterminate state in permission modal

When selecting "Select All" for a specific permission group, the "Grant All Permissions"
checkbox should display an indeterminate state if not all permissions are granted.

The issue was that GrantAll and GrantAny were calculated based on _groups (filtered list)
instead of _allGroups (all groups), causing incorrect checkbox state when groups were filtered.
