feat(backend): Lagerbehälter-Umlagerung für Honigchargen (Modul 32)

Neues HoneyBatchRelocation-Modell dokumentiert jede Umlagerung einer
Honigcharge zwischen Lagerbehältern (von/nach, Zeitpunkt, Benutzer,
Notiz). HoneyBatchesService.relocate() aktualisiert
HoneyBatch.storageContainerId transaktional zusammen mit dem
Historieneintrag; wirft NotFoundException bei unbekanntem Zielbehälter.

Neue Endpunkte: POST /honey-batches/:id/relocate,
GET /honey-batches/:id/relocations. honeyBatchInclude liefert jetzt
zusätzlich den aktuell zugeordneten storageContainer mit.

Unit- und E2E-Tests ergänzt (Mehrfachumlagerung, Historienreihenfolge,
404 bei unbekanntem Behälter). Migration auf Dev- und Test-Datenbank
angewendet.
