fix(scripts): update.sh never applied litellm-pgvector's db schema

litellm-pgvector's Dockerfile only runs 'prisma generate' (codegen) at
build time — nothing ever ran 'prisma db push' against pgvector-db, so the
vector_stores/embeddings tables plain didn't exist on a fresh deploy. Every
vector store call failed with 'relation "vector_stores" does not exist'.

update.sh now runs the push itself after bringing litellm-pgvector up.
