feat(management): FlowDebug run-method / run-value-change / replay commands (Deployer, active-node gated, inline trace)

Flow Debugger (design 2026-09-05 §7.1): FlowDebugRunMethodCommand / FlowDebugRunValueChangeCommand /
FlowDebugReplayCommand on the per-node ManagementActor (Deployer role; the two run commands
are long-running), all delegating to FlowDebugRunner. RunMethod refuses on a standby with
STANDBY_NODE (ManagementCommandException now carries an optional Code that replaces
COMMAND_FAILED), validates parameters through the real ParameterValidator/SchemaRefResolver
(made public), synthesizes the inbound row (actor = operator, Extra.source = flow-debugger)
and runs the method through InboundScriptExecutor with a trace-sink RouteHelper so the reply
carries the RouteCall row + the site's inline events. RunValueChange does a traced routed
write via IInstanceRouter, then polls IPullTraceEventsClient (interface moved to Commons so
ManagementService can consume it) until a ScriptRun parented to the root settles, else
NO_TRIGGER_WITHIN_WINDOW. Replay reads IAuditLogRepository.GetTraceEventsAsync.
