Review inbox: show each AI action, result, and the run log

Restructures each held item into Action -> Result -> Run log:
- Action: a clear statement of what approving does (write artifact + N child tasks),
  with a destructive warning where relevant.
- Result: the editable proposed artifact + child tasks (with the edit diff).
- Run log: lazily fetches the AgentRun and shows latency, the agent/autonomy, skills
  applied, available + actually-called tools (with ok/failed), memory hits, product-
  identity inclusion, and collapsible raw model output + assembled prompt.

Enriches the assembler run endpoint (Trace, ResultJson, LatencyMs, timestamps) so the
approver can see exactly how the agent reached its result before deciding.
