fix: populate assistant_id from config configurable instead of metadata

[open-swe]

Description

Ports the equivalent change from langchain-ai/langgraph#7468 to langgraphjs. The _buildServerInfo function was reading assistant_id and graph_id from config.metadata, but the server puts these values in config.configurable. This updates the source to read from configurable consistently. Also adds the missing assistant_id to the embed API's createStubRun configurable to match the full API behavior.

Test Plan

• Verify serverInfo.assistantId and serverInfo.graphId are correctly populated from config.configurable
