Remove hardcoded "Created by fab" description from mkdir and import commands

[HasanAboShally]

Description

When creating items, workspaces, folders, or connections via mkdir, the CLI hardcodes "description": "Created by fab" in the API payload. Similarly, import hardcodes "Imported from fab". Users have no way to override or opt out of this description.

This is problematic because:

• Users may not want a default description on their resources
• Downstream services may propagate this description to child objects, causing unexpected metadata pollution
• The CLI should not stamp metadata that the user didn't explicitly request

Affected files

• src/fabric_cli/commands/fs/mkdir/fab_fs_mkdir_item.py
• src/fabric_cli/commands/fs/mkdir/fab_fs_mkdir_workspace.py
• src/fabric_cli/commands/fs/mkdir/fab_fs_mkdir_folder.py
• src/fabric_cli/commands/fs/mkdir/fab_fs_mkdir_connection.py
• src/fabric_cli/commands/fs/impor/fab_fs_import_item.py

Proposed fix

Remove the hardcoded "description" field from the API payloads so that resources are created without a default description unless the user explicitly provides one.

Existing since

v1.1.0 (initial release)
