Gulum 4aca1d528b EXTRACT band-aware Farbschlag: deep bands (gen>=2) have no colour cell ...

Julian-confirmed against the real xlsx (Kentucky, Akio Kids): pedigree
blocks have two shapes. EARLY bands (gen 0-1, cols B/E/H) are 5-cell
Name/DOB/Farbschlag/Genotype/Zucht — real Farbschlag present. DEEP bands
(gen>=2, cols K/N/Q...) are 3-cell Name/DOB/Genotype with NO Farbschlag —
the colour is derived from the genotype.

The old extractor grabbed the NEXT block's name or a stray health note
(e.g. "DD-Tumor", "Chronische Ohrenentzündung...") as the deep-band
Farbschlag — source of the D1 'name-in-Farbschlag' conflicts and a big
chunk of farbschlagUnmatched. Fix: gen_of(col)>=2 => never assign a
Farbschlag in that block (Name/DOB/Genotype only); the cell is left for the
next block's name search. Deep-band animals load with empty Farbschlag and
the UI computes 'Errechnet' from the stored genotype (lossless).

Dedup already prefers a real (non-empty) early-band Farbschlag, so an animal
appearing in both an early band (Chesnut -> 'Kohlfuchsschimmel') and deep
bands keeps the real value; Chesnut and Tennessee stay separate (distinct
genotype + name+DOB key).

Result: 248/306 loadable animals now have empty Farbschlag (genotype-
derived), 0 suspicious name/note values remain, 0 Farbschlag-based conflicts
(D1 dissolved). Regression test test_extract.py builds a two-band xlsx and
asserts the deep band yields no Farbschlag + the stray note doesn't bleed.

Extractor-only (no C# change). python test_genotype + test_extract green;
dotnet 118/118. Batches with Kevin's GEN-3f seed for one re-import.
