Your new experiment (attraction rather than alignment) simplifies things somehow (no torque, just linear acceleration), but let's stick to the non-wire-resistive loop shall we, it makes things simpler, and closer to the electron orbit or spin counterpart you are comparing it to.
1/ Using an external current source, let's start a constant current through the loop. 2/ Zero wire resistance, zero radiation resistance, constant current so zero auto-induced voltage -L*di/dt, so zero voltage drop. This means we can connect the loop back on itself and remove the current source without stopping the current ok? Let's do that, so that loop voltage will remain zero for ever, and define this as time zero for the energy balance. 3/ Now let's release the magnet. It should indeed be attracted and accelerated towards the short-circuited current loop so KE will be gained, but how could the energy be drawn from the loop if voltage is zero?
