PAI Access Fix (#2707)

Fixes a bug that gave PAI's all access.
It seems at some point silicons were changed to use an internal ID, and pais were given that same ID which had all access.

Changed it so their internal ID only has basic access and rerouted pai ID functions to it. This restores them to intended functionality, that is: They can only walk in public areas, and wherever their master has access, once the master has scanned their ID
