📄 Description

Changes made:

Use BRPOPLPUSH to move a task from a queue to In-Progress list
Remove a task from In-Progress list once a worker has finished with the task
On start, pushes the In-Progress tasks (if any) back to the queue

This change makes the system more resilient. It prevents data loss in case there's a server crash while workers are still working on a task or a task is waiting for an available worker.
