fix(import): Farbschlag aus Genotyp ableiten + Mamta-Eltern — Ticket-Triage

genotype.py: Python-Port von genotypeToFarbschlag (0 Abw. über 3402 Genotypen).
resolve_color_and_genotype: bei vorhandenem Genotyp gewinnt der berechnete Farbschlag
(Goldfuchs≠Gold, Dilute Agouti/Anthrazit, Blaufuchs statt -schimmel bei (schimmel),
spsp statt Schecke). Mamta Mini: Ee + Eltern Geely×Gaida am Wurf. Regressionstests je Fall.
