K8s profile relied on shared/dev defaults for spring.datasource.url, but those live inside the dev profile block — invisible when k8s profile is active. Result: 'APPLICATION FAILED TO START — Failed to configure a DataSource'. Move full datasource (and kafka/redis for projection-writer) wiring into the k8s profile section. ENV vars come from Vault Agent injector (ORDINIS_PG_USER/PASSWORD, ORDINIS_KAFKA_USER/PASSWORD, ORDINIS_REDIS_PASSWORD) and chart-supplied ENV (ORDINIS_PG_HOST, ORDINIS_KAFKA_BOOTSTRAP, etc).
