- Add Agents section to subscriber Command popover (members + agents both selectable)
- Fix subscriber matching to use both user_type and user_id (prevents cross-type collisions)
- Add max-h-64 to CommandList to prevent overflow
- toggleSubscriber now accepts userType parameter for proper agent support
