fix: Add explicit foreign_keys to User.containers relationship

Browse Source 
SQLAlchemy konnte nicht bestimmen welcher FK gemeint ist, da UserContainer
zwei FKs zu User hat (user_id und blocked_by).

Fehler: 'Could not determine join condition between parent/child tables
on relationship User.containers - there are multiple foreign key paths'

Lösung: foreign_keys=[user_id] explizit angeben.
