Include connector IDs in MCP tool call analytics (#32867)

## What changed

- Add the optional `connector_id` to `codex_mcp_tool_call_event` parameters.
- Populate it from the MCP tool call's `app_context` when available.

## Testing

- Extend the completed tool item analytics test to verify the connector ID is serialized.
