hailin 70d1a8bfb8 fix(referral): add idempotency check for Kafka event processing 
- Add processed_events table to track handled events
- Check eventId before processing planting.created events
- Skip duplicate events and still send ACK to stop retries

This prevents data accumulation when Kafka events are redelivered
due to ACK failures or consumer timeouts.
