test(rashi-dashas): compare with PyJHora on the same Lahiri chart

The frozen comparison put an engine-default (Raman) native chart next to a
LAHIRI PyJHora chart, so half of every recorded difference was ayanamsa.
Both the freezer and the test now pass ayanamsa_name=lahiri; the fixture and
the progress diff table are regenerated. Report code is unchanged.
