Update services that rely on /pop endpoint of scheduler

[jpbruinsslot]

Background

• Issue: Combine all schedulers for all organisations #3838

Description

The following changes introduced in PR: Combined Schedulers must be reflected in all services that rely on the /pop endpoint of the scheduler.

Key Changes

The /pop endpoint has been updated as follows:

1. Endpoint Path:
   The endpoint has changed from /queues to /schedulers/{id}/pop.

2. Response Format:
   Instead of returning a single task, the endpoint now supports filtering and returns a paginated result with multiple tasks.

Impact on Services

Services using the /pop endpoint must update their interfaces to align with these changes. This includes:

• Updating endpoint paths in API requests.
• Modifying handling logic to support paginated responses and task filtering.
