fix(watchdog,priority,dns_failover,providers): reduce CPU/memory footprint on low-end routers (1.3.20)

Browse Source 
- priority.uc: replace 1s tight sleep loop with dynamic interval based on group config (5s default)
- dns_failover.uc: replace 1s sleep with min(active_interval, recovery_interval)
- watchdog.uc: cap pending_smart_domains at 500 entries, add 300s TTL expiry
- event_controller.uc: batch is_dns_working nslookup calls into single shell process
- byedpi/runtime.uc: add crash-loop backoff (up to 6x base delay after 5 rapid crashes)
- nfqueue/runtime.uc: same crash-loop backoff for nfqws supervisors
