Add configurable PodDisruptionBudget support to all Helm charts in the self-managed stack. Each chart gains a podDisruptionBudget values block (enabled: false by default) that operators can activate in their environment file to protect against simultaneous voluntary evictions during node drains, cluster upgrades, and autoscaler events. Infrastructure (cassandra, nats, openbao): - cassandra: new PDB template + values; wired in global.yaml.gotmpl - nats: expose upstream chart podDisruptionBudget in wrapper values - openbao: expose server.ha.disruptionBudget; make injector PDB configurable Control-plane services (13 charts): - Add podDisruptionBudget.enabled/minAvailable/maxUnavailable to values.yaml - Add poddisruptionbudget.yaml template gated on enabled flag - Affected: ess, grpc-proxy, http-invocation, ratelimiter, llm-api-gateway, llm-request-router, admin-token-issuer-proxy, api-keys-colocated, nvca-operator, nats-auth-callout, function-autoscaler, helm-reval, container-cache (values only) Stack wiring: - global.yaml.gotmpl: passthrough for cassandra, nats, openbao PDB values Docs: - Add docs/user/pod-disruption-budgets.md with configuration reference - Link from optional-enhancements.md and fern nav

Operators running NVCF self-managed on managed Kubernetes clusters (EKS, GKE, AKS) need PDBs to prevent voluntary evictions from taking down entire stateful tiers (Cassandra, NATS, OpenBao) during node drains and cluster upgrades. Without PDBs, a single node drain can evict all three Cassandra pods simultaneously, causing an outage.
Charts changed
Infrastructure — cassandra (new template), nats (upstream passthrough), openbao (upstream passthrough + injector configurable)
Control-plane services — ess, grpc-proxy, http-invocation, ratelimiter, llm-api-gateway, llm-request-router, admin-token-issuer-proxy, api-keys-colocated, nvca-operator, nats-auth-callout, function-autoscaler, helm-reval, container-cache (values only)
