Changes to dcmotor:
...
- Remove `lugre:viscous`, should now be added directly to actuator `damping`. Trying to do this for the user was incompatible with default inheritance (compounding instead of overriding).
- Move voltage limiting from the `saturation` to the `controller` attribute.
- Fix indexing issues in default inheritance.

The introduction of site specification to connects and welds in 3.2.3 conditionally changed the semantics of `mjData.eq_obj1id` and `mjData.eq_obj2id`. These changes were not properly propagated in several places leading to incorrect computations of constraint inertia, readings of affected force/torque sensors and runtime enabling/disabling of such constraints.
