[Bug]: Worker stops picking up tasks for duplicate key

**Describe the bug**
Monitor had timeout and has not reported in multiple days

**Database**
- postgresql

**To Reproduce**
Not sure how to reproduce looks like there was some sort of error in Redis/Postgres and now a duplicate key exists and the worker is no longer picking up from the queue to check the site

**Expected behavior**
The system should be able to recover even with duplicate key and continue health checks

**Screenshots**

^ Can see that the worker stopped 3 days ago after reporting DOWN

Producer logs showing duplicate entry in the Queue service

Ingester showing both duplicate in queue service and a pg error

Worker successfully picking up one monitor but not the one that is erroring out

**Additional context**
This is running inside Kubernetes using a Postgresql and Redis from Bitnami but I would imagine this scenario is not related and seems to be more of an issue with inserting / retrieving information from Redis/Postgresql

O issue envolve um sistema de fila de workers usando Redis e PostgreSQL. Examine o serviço de fila e o código do worker para lidar com chaves duplicadas e erros de banco de dados. Analise os logs do ingester e do produtor para entender o fluxo de falha. A correção provavelmente requer a modificação da lógica de tratamento de erros e recuperação nos componentes de processamento da fila.
