Replace synchronous RPC-based CP-host communication for sandbox lifecycle operations (Create, Pause, Resume, Destroy) with an async pattern. CP handlers now return 202 Accepted immediately, fire agent RPCs in background goroutines, and publish state events to a Redis Stream. A background consumer processes events as a fallback writer. Agent-side auto-pause events are pushed to the CP via HTTP callback (POST /v1/hosts/sandbox-events), keeping Redis internal to the CP. All DB status transitions use conditional updates (UpdateSandboxStatusIf, UpdateSandboxRunningIf) to prevent race conditions between concurrent operations and background goroutines. The HostMonitor reconciler is kept at 60s as a safety net, extended to handle transient statuses (starting, pausing, resuming, stopping). Frontend updated to handle 202 responses with empty bodies and render transient statuses with blue indicators.
