ci: add explicit build-deploy step for drive-integration

drive-integration is a private lerna package and is excluded from lerna's
--since scoping, so its deploy script was never called by CI. Add a dedicated
step in build-deploy-prod that builds the frontend with the correct Vite env
vars and runs upload:app-prod + deploy:sync-prod directly.
