chore: remove code nothing uses

- is_yahoo_safe, has_checkpoint, get_wall_times, the graph's curr_state and the project_dir config key
- the CLI's final_report and current_agent state, its duplicate get_analysis_date and the save_report_to_disk wrapper
- the dotenv import guard (a hard dependency) and a warning filter for langgraph-checkpoint 4.0.3
