I am aware of the proposition that clocks actually slow down relative to motion wrt space (you refer to the substantive stuff as fields - but the idea is the same) And as it turns out, one can explain most relativistic effects in terms of actual clock slowing as per Lorentz.
But most relativistic phenomena can also be explained using traditional SR (totally kinematic). SR struggles with the triplet problem which all SR adherents claim to be non paradoxical.. that is, so they say, "if you really understand SR" - but the reasoning is convoluted, and always leaves me with the feeling that resolution is postulated rather than derived - on the other hand, Lorentz Ether requires actual physical contraction - which to my way of thinking creates serious conceptual problems - and it requires adherence to a different belief system which is for me just as hard to accept.
Anyway - I am still not convinced from your post that Einstein ever went so far as to endorse a physical mechanism to explain Gravitational time dilation - as I read his works and the many interpretations thereof, I cannot find a foundational underpinning for a physical cause in the Special or General theory per se.
I Assume you are familiar with the various spatial "inflow" theories.
They do a good job of tying gravitational time dilation to the effective escape velocity (the rate of inflow determines the escape velocity and this rate corresponds to the time dilation due to this velocity vis a vis SR). Tom Martin has published several papers dealing with experiments that - if performed, will either validate GR and falsify Spatial inflow - or vice versa.
