Felt Orbit - single knob jump isolation fix

Based on the supplied knob_isolation_fix version.

The raw knob `change` detector is now BEFORE the active-page spigot for each of the four knobs.
This lets each detector silently track its own physical knob while Felt Orbit is inactive, without sending anything to the parameter or star paths.
When Felt Orbit becomes active again, an ORHACK refresh/broadcast of all four raw knob values is therefore ignored for knobs that did not actually move. Only the physically moved knob passes through and jumps to its current position.

No star abstraction, parameter scaling, defaults, audio patch, or animation logic was modified.
