Work is performed indeed by the magnet, but why conclude that total
energy of
the system hasn't been conserved?

If the clip is lifted by a chemical reaction to the same height, you
would have conventional conservation. The magnet might be
conservative; but, not by any "conservative" explanation. :-)
My point is simply that if you use an electromagnet to lift the clip,
the Lorentz explanation holds and you clearly have a relativistic
effect. However, if the clip is lifted by the spin magnetic momentum
of an unfilled electron shell, we have an entirely different case, a
quantum effect. As posted earlier, these forms of magnetism are not
equivalent.
Permanent magnet work might be an exchange between ZPE and mass, as
Robin opines.
This discussion is not dissimilar to Puthoff's explanation of why the
electron in angular accelerating around the hydrogen nucleus does not
radiate and collapse into the nucleus.
