Delete the stop-monitoring dialog plus the retired per-type settings
shells now that the unified ConnectionEditor replaces them: remove
PlatformConnectionsWorkspace / ProxmoxSettingsPanel /
ProxmoxDirectWorkspace / NodeModal et al and the accompanying tests.
Strip the lingering reporting-state hook from
useInfrastructureOperationsState and the guardrail test reinforces the
removal. Reconcile registry.json, frontend-primitives.md,
api-contracts.md, agent-lifecycle.md, status.json, and the
release-control guard/test fixtures so governance audits stay clean.
