feat(backend): Koeniginnenbewertung (Modul 31)

QueenEvaluation-Modell (Volksstaerke, Sanftmut, Wabensitz, Schwarm-
trieb, Brutbild, Honigertrag je Skala 1-5) als Sub-Ressource der
Queens-API: GET/POST /queens/:id/evaluations. Vorgezogen vor Modul
27 (Statistik), da dessen Koeniginnen-Auswertungen auf diesen Daten
aufbauen.
