feat: make scraper and job service account-aware

- OptimizedTelegramScraper accepts account_id parameter;
  sets DATA_DIR to data/accounts/<id>/ when provided
- Session path uses account_session_path() for per-account session files
- initialize_client() reads per-account credentials from account state store
- ScraperJobService passes account_id from payload to scraper constructor
- Per-account state loaded from AccountStateStore before scraping
