Force-enable leg IK when foot driver active, fix gizmo visibility

Desktop mode never sets HasRigLayer on foot bones (only trackers do),
so EnableLeftLeg/EnableRightLeg stayed false and the IK solver skipped
legs entirely. Now force-enables leg IK per-frame in
SimulateIKDestinations when the foot driver is initialized and not
seated.

Moved foot gizmos from OnDrawGizmosSelected to OnDrawGizmos so they
render without requiring the EventDriver to be selected in hierarchy.
