The dashboard chat sidebar's tool-call activity card was disabled in the
product — both ChatPage mounts passed showTools={false} (since #49077),
so the box never rendered. The sidebar still subscribed to tool.* events
and accumulated them in state for a panel nobody saw.
Remove the tools card, the showTools prop, the tool.* event handling and
state, and the now-orphaned ToolCall component. The /api/events
subscription stays for session.info (live title) and
dashboard.new_session_requested. The sidebar is now just the model
selector box; the session list (ChatSessionList) is unchanged.
No behavior change in the live dashboard — the tools box was already
hidden.
