feat(agent): initialize checkpointer before chat session retrieval

Browse Source 
Add initialization check for `_checkpointer_conn` in `AgentService` to ensure the checkpointer database connection exists before attempting to retrieve chat sessions. This prevents potential null reference errors when the checkpointer hasn't been initialized yet during agent operations.
