feat (wind_direction): support the new measurement_angle state class

Around 2025.5 HA quietly introduced a new measurement_angle state
class that is not referenced in the developer blog or release notes,
though documentation changes were submitted in late February well before
the code changes, so it was documented.

HA is raising warnings if measurement is used for wind_direction, so
use the new state class.
