Fix template evaluation timeouts and add retry logic

- 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
