fix(app): switch hibernate ddl-auto to none in k8s profile

Hibernate validate mode threw 'wrong column type [supported_locales]:
found [_text (Types#ARRAY)] but expecting [text[] (Types#OTHER)]' against
the Liquibase-managed schema. This is a well-known hypersistence-utils +
PostgreSQL TEXT[] friction with Hibernate validate.

Schema is owned by Liquibase migrations; validate adds no safety here. Set
to 'none' (matches read-api and projection-writer).
