Add support for "Open door" button in Matter for Nordics lock, and "Choose door fitting" setting

Product name

Smart Lock Ultra Nordics

Summary

As described here, there is some confusion about using the Nordics lock for doors without the handle outside. In order to be usable, the lock must both unlock the deadbolt and pull the latch. It can be done via the “Open door” button in the Nuki app, but it is not possible to reorder the buttons, so that it is not hidden by default. And it is completely not possible to use it via Matter (in Home Assistant) because the open door button does not appear here for this lock.

For the standard Ultra lock, it is possible to choose “knob or bar” in the “Choose door fitting” setting, and after that the buttons will be reordered and the “Open door” button will appear in Matter.

Features

Add support for “open door” in Matter for this lock. I guess the ideal solution is simply adding the “Choose door fitting” setting, like in the standard Ultra lock.

Reason

The lock technically seems to work fine for such doors, but it is not possible to use it via Matter, and in the Nuki app it is also a bit confusing, since the button is hidden below the screen.
