Implement n8n workflow import logic in secret generation script

- Added RUN_N8N_IMPORT_COMPLETE variable to .env.example to track the completion status of n8n workflow imports.
- Updated 03_generate_secrets.sh to manage user prompts for importing workflows and preserve the import status across sessions.
- Refined the logic for determining whether to prompt the user for importing workflows based on previous completion status.
