Add lockState support to vehicle properties (#83)

Hello,

I’d like to propose a small improvement to vehicle properties handling.

This change adds support for the vehicle door lock state (lockState) by:
- Including lockState in the VehicleProperties type
- Reading the value using GetVehicleDoorLockStatus in getVehicleProperties
- Applying the value using SetVehicleDoorsLocked in setVehicleProperties

This allows vehicle lock status to be properly saved and restored alongside other vehicle properties.

Let me know if this fits the project direction or if any adjustments are needed.

Note: Two additional commits and pull requests were accidentally opened during this process and have already been closed. Sorry for the noise.

Thank you!
