The conditional config.debuglogging checks were not working reliably
in node_helper context. Removed debug logging from onStateChangedEvent

second for power sensors). WS disconnect promoted to info level since
it's actually useful.
- Add 10 second timeout to template evaluation HTTP calls
- Add retry logic that schedules retry after 30 seconds on failure
- Maintains existing error handling while preventing silent failures
- Fixes issue where template errors cause data to stay stale until next WebSocket event
