Check the kernel logs ("dmesg") for any errors. Check if the dummy_sensor module is loaded with "lsmod". Check if it has been built with "modinfo dummy_csi_sensor".
The fact that "v4l2-ctl --list-devices" is saying unicam is registered but with no /dev/video node means that it is waiting on some dependency. You can also check /sys/kernel/debug/devices_deferred and (something like) /sys/kernel/debug/v4l2_async will tell you if the system is waiting on some devices.
I'm in the middle of some other work, but I am rebasing my dummy_sensor branch onto 6.6, as 5.15 is pretty old now.
