STAMMBAUM-LITTERS: Wuerfe des Wurzeltiers links im Stammbaum-Viewer

Layout: stammbaum-layout (flex-row Desktop / flex-column Mobil) wraps [Wuerfe-Panel | Canvas]. Panel 148px breit, border-right Trenner; auf Mobil (<=520px) horizontaler Scroll-Streifen ueber dem Canvas. Daten: useApi(listLitters fatherId=id|motherId=id) reagiert automatisch auf Umwurzeln (id-Param). Kein Panel wenn Wurzeltier keine Wuerfe hat. Pro Wurf: Wurfname (fett) + N Junge + Link zu /wuerfe/{id}. CSS: flex 0 0 auto Mobil-Override sichert Canvas-Hoehe im column-Mode. de.ts: littersTitle, littersJunge (Stammbaum-Sektion, disjunkt). Gate: vitest 122/122 e2e 20/20 Stammbaum (4 neue Tests x 2 Viewports) build+tsc+eslint clean.

+ * GEN-3h: sub-alleles use breeder bracket notation (e[f], c[chm], c[h]);
+ * E-locus display order is E > e > e[f] (e before e[f] in het pairs).
