I've noticed my Home Assistant Matter integration to crash when connecting a device flashed with the MatterContact example. Please see related issue for more details.

I've traced this issue back to MatterContact and MatterDoorLock using incorrect attributes of type INT8U instead of BOOLEAN as specified in the Matter 1.4 Application Cluster Specification.

Please note that this PR may not be complete. I didn't do an exhaustive scan for further incorrect attribute types.
