Hermes Agent service account e8303d5129 Fix Talos iSCSI configuration for Portworx CSI 
Root cause: Previous config violated boot-time security model
- Removed /etc/iscsi mount (iscsi-tools extension manages it)
- Moved multipath.conf to post-boot DaemonSet
- Added explicit kubelet nodeIP for dual-NIC workers

Deliverables:
- Fixed talconfig.yaml with working worker patch
- iscsi-multipath-init.yaml DaemonSet for multipath config
- Automated deployment and verification scripts
- Complete documentation suite

Ready for production deployment to fastpass worker nodes.
