Pull request overview

This PR implements automatic task cancellation when resources are deleted, improving data consistency by preventing orphaned tasks from attempting to operate on deleted resources.

Key changes:

• Added a resourceId column to the tasks table to enable efficient querying of resource-related tasks
• Implemented cancelResourceTasks() method to cancel all active tasks associated with a deleted resource
• Integrated task cancellation into the resource deletion workflow
• Renamed cancelTask() to cancelTaskOrFail() for clarity
