feat(management): Flow Debugger inbound row carries exception detail; LogsTruncated on the run result

FlowDebugRunner.RunMethodAsync now passes InboundScriptResult.ErrorDetail through to the
synthesized inbound audit row's errorDetail, so a SCRIPT_ERROR run's exception ToString() lands
on AuditDetails.ErrorDetail for the Flow Debugger's inbound node to read (never surfaced to the
HTTP caller). FlowDebugRunResult grows an additive LogsTruncated (default false, last positional
member) reporting the inline FlowTraceCollector's low-priority (ScriptLog) truncation separately
from Truncated (step-row fidelity); RunMethodAsync/RunScriptAsync thread collector.LogsTruncated
through on their two collector-backed results.
