fix(import): Stammbaum-/Eltern-/isResident-Tickets der Züchterin (18)

Import-Logik:
- Externe Gründer (Zooladen/„von Privat"/„from …, <Land>") bekommen keine
  erfundenen Chart-Eltern mehr → Bill, Cooky, Zadar haben korrekt unbekannte
  Eltern (is_external_origin). [#5,#13,#28]
- Hagrid: externe Zucht wird nicht mehr als Bestand markiert (isResident=false)
  + Leerhüllen-Dedup → ein Datensatz mit Eltern Snickers × Milka. [#17,#18,#20a]
- Gender-Index: eindeutiges Geschlecht schlägt unbekanntes Duplikat → Rollen-
  Auflösung repariert (Vance→Mutter Enya, Zac→Vater Vance/Mutter Dorie). [#33,#35]
- „Eltern: X + Y"-Wurfnotizen werden geparst (~46 Würfe); v.d.↔von-den-Namens-
  kanon (Theodore→BlackFire). [#9,#11,#30]

Daten-Overrides (conflict-decisions.json, jetzt auch Gender + exakte Eltern):
- Mozart→weiblich [#2], Yuki=Camaro×Izumi [#23], Gold-Mutter=Chelsea [#36],
  Arya=Vance×Sansa (Geschwisterverpaarung) [#16], Tony→Sammy [#12],
  Odelia [#15], Jamie→Danny [#31], Silver=Taro×Beatrice [#11].

Frontend: GerbilDetailPage blendet für isResident=false Würfe + Charakter aus
(Hinweis nonResidentNote). [#17,#20b]

Tests: test_extract/test_merge_resolve erweitert; vitest 135, playwright tiere 34 grün.
