[feature:gsoc26] Batch command execution and confirmation admin workflow

Is your feature request related to a problem? Please describe.
Currently, commands can only be executed for individual devices from the admin interface. With the introduction of asynchronous batch command execution, administrators need a dedicated workflow to select target devices, configure the command, preview affected devices, and confirm execution before creating a BatchCommand operation.

Describe the solution you'd like
Implement a custom Django admin workflow for creating a batch command based on the proposed Figma design. The workflow should allow administrators to:

Select target devices using different scopes:

• All devices
• Organization
• Location
• Device group
• Manual device selection

Filter available objects based on organization selection to respect multi-tenancy. Preview the resolved target devices before execution in the confirmation page and then select the command type and execute this will create the BatchCommand object after correct confirmation and execution and redirect the user to its admin detail page.
