Expanded Logs rows show the trace's duration, LLM calls, tokens, tool calls
and retrieval time, and open a side panel with a waterfall of every step:
retrieval, embeddings, per-source searches, model calls and tool calls,
with each step's details, previews and raw attributes. Chat turns paused
for approval show one waterfall per round. Searches and graph builds get
their own log types. Strings are translated in every locale.
