Merge feature/ui-polish-2: '(ohne Namen)'-Platzhalter in Stammbaum + VertragWizard + WurfForm

Namenlose Stub-Tiere zeigen jetzt ueberall '(ohne Namen)' statt leer: Flagship-Stammbaum
(Karten+Druck+Header), Vertrags-Assistent, Wurf-Formular. +2 e2e (namenloser Ahne im Stammbaum).
vitest 82, e2e 148, build clean. Kein EF.
