🐛(helm) add default commands for celery workers

Without explicit commands in values.yaml,
celeryTranscribe and  celerySummarize pods
were using the Dockerfile's default CMD (uvicorn),
which started the REST API instead of Celery workers.

This fix adds default commands to values.yaml for both services,
ensuring they run as Celery workers processing their respective
queues (transcribe-queue and summarize-queue).
