Match meta-predictor's working WES pattern

- Add executor, docker, k8s storage config to k8s profile
- Use val input instead of file channel (avoids S3 staging issue)
- Pass PDB path as string, copy from PVC mount inside script
- Add PVC mount debug logging
- Set default params to /omic/eureka paths
