Expand the Node Loss section in block-storage.md to accurately describe the automatic fencing flow, and add dedicated Network Fencing sections across the CSI documentation to provide configuration examples for both manifest-based and Helm-based deployments. * block-storage.md: introduce the Network Fencing prerequisite paragraph with links to the new example sections, replace the single-line "auto-fencing" description with three bullets describing the client blocklist flow, and update Node Recovery to a single sentence covering workload rescheduling and the 5-minute cool-down behavior that triggers automatic unblocklist. Add a Warning admonition instructing administrators not to remove the out-of-service taint before the node completes a full power cycle. * csi-configuration.md: add a Network Fencing section enumerating the three prerequisites (CSI-Addons controller, CSI-Addons sidecar, enableFencing flag) and showing the RBD Driver CR manifest with deployCsiAddons and enableFencing set together. * csi-drivers-chart.md: add a Network Fencing subsection under Custom settings showing the per-driver Helm values for deployCsiAddons and enableFencing, with a cross-reference to csi-configuration.md. * ceph-csi-drivers.md: replace the legacy CSI_ENABLE_CSIADDONS configmap patch in the Enable CSI-Addons Sidecar section with the modern deployCsiAddons approach on OperatorConfig or Driver, and add a Network Fencing overview section that links out for configuration details and the operational flow.
