config: add verification and schedule settings

- [verification] section: enabled, threads, batch_size, interval, max_queue
- working_checktime: retest interval for working proxies (default: 300s)
- fail_retry_interval: retry interval for failing proxies (default: 60s)
- fail_retry_backoff: linear backoff for failures (default: True)
- ssl_only: skip secondary check on SSL failure (default: False)
