fix(event/stream): classify AXIS VMD 3 topics as motion

Browse Source 
VMD 3 is the firmware-builtin motion rule, published as
tns1:RuleEngine/tnsaxis:VMD3/vmd3_video_<N>. It predates the VMD 4 ACAP
and lives under RuleEngine rather than CameraApplicationPlatform, so the
VMD 4 rule added in the previous commit does not cover it.

Confirmed against a deployed AXIS camera: with debug logging on, its
event stream emits vmd3_video_1 on every motion trigger, and every one
was discarded as KindUnknown.

The VMD 4 rule stays — both generations are in the field.
