Django Async Task Conflict Prevention for PowerCRUD

By introducing async processing we introduce potential conflicts. Also want to allow downstream project developers to use the same base mechanism for conflict detection, in case they want to run async processes independent of powercrud (eg save() method that updates child and descendant objects) but want overall conflict detection.

Problems to Solve

Lock conflicts - preventing simultaneous updates to same objects
User state confusion - users making decisions based on stale data while async tasks are running
Race conditions - timing-dependent bugs in concurrent operations
Complex dependencies - bulk operations, single saves with descendant updates, and async tasks can all affect overlapping sets of objects
Downstream flexibility - powercrud needs to work with any downstream project's specific object relationships

Problem Description

When attempting to submit the bulk edit form within the modal, an htmx:targetError is encountered in the browser console. This error indicates that the HTMX target element, <div id="powercrudModalContent"></div>, is missing from the Document Object Model (DOM) at the time of the form submission.

Migration from sessionStorage to Django Sessions for Bulk Selection

The current bulk selection system uses browser sessionStorage which prevents server-side manipulation of selected items. We need to migrate to Django sessions to enable backend control over selection state.

Plan for Background Processing for Long-Running Tasks

The current bulk edit functionality is synchronous and can take 30+ seconds for large datasets, creating poor UX with browser timeouts and user confusion. We need to implement asynchronous processing with progress tracking and user notifications.
