In other words, what are the action-reaction force pairs involved here?

Ficticious forces in non-inertial coordinate systems do not have action-reaction pairs. For instance, there is no reaction force to the centrifugal force in a rotating reference frame. So adding the ficticious centrifugal force helps Newton's 2nd law to work, but causes Newton's 3rd law to fail.

In the end there is no such thing as field, there is only interaction between charges.

I certainly would not make such a statement. The fields carry momentum and store energy so trying to claim that they do not exist will ruin all of your conservation principles. I don't know what criteria you would use to say that they don't exist.
EDIT: On the other hand, they are frame variant quantities. In that sense they are more like energy or time than mass which is invariant.
