No direct link between Task/Project and Cloud Storage after data import

Actions before raising this issue

• I searched the existing issues and did not find anything similar.
• I read/searched the docs

Steps to Reproduce

1. Create Test Project

2. Create Test Task and attach files from connected cloud storage

3. Check Project/Task After create and annotation

Expected Behavior

When importing data from a cloud storage to a task, there is no persistent link between the task/project and the source cloud storage. After successful import, the source_storage field in both project and task objects shows location: 'local' with an internal storage ID that doesn't reference the original cloud storage.

The task and project should maintain a reference to the original cloud storage after import. Expected source_storage field:
'source_storage': {
'cloud_storage_id': 254, # Original cloud storage ID
'location': 'cloud_storage'
}

Possible Solution

No response

Context

After import, source_storage always shows location: 'local' with internal storage IDs (4321, 4322, 4329, 4330 and so on) that have no relation to the original cloud storage ID (254) - despite confirming that the data was explicitly imported from the cloud storage during task creation.
This creates several issues:

No traceability - Cannot determine which cloud storage contains the original data

Multiple storage entries - Each task/project creates new internal storage entries with different IDs

Lost connection - No way to programmatically find related cloud storage for a task
