Requirement: Form and DB Operation 9 - Bulk Permanent Delete & Global Selection

This exercise upgrades the list view to support cross-page selection and bulk permanent deletion, simulating a professional administrative interface for managing records.

NOTE: The global selection and multi-page logic are implemented, but the Bulk Delete button is configured for **Permanent Delete** (Hard Delete), which was the final state before the last feature request (which is not implemented here).

List Setup & Pagination:

• The list is paginated (5 records per page) and sorted by Name (Ascending).
• The default data set is large enough to span at least two pages.
• A checkbox column is added to the table with a Select All header checkbox.

Global Selection & State Management:

1. Global Selection: When the Select All checkbox is checked, it must select all records in the currently filtered set, regardless of which page they reside on.
2. Cross-Page Persistence: Navigating between pages must maintain the selection state of previously selected records.
3. Dynamic Select All: The Select All header checkbox must dynamically check/uncheck based on whether all records in the current filtered set are selected. Unselecting any record on any page should uncheck the master selector.
4. Delete Button Count: The Delete Selected button must accurately display the total number of records selected globally (across all pages).

Bulk Delete Functionality:

1. A Delete Selected button is placed near the search bar.
2. The button executes a Permanent Delete (Hard Delete) operation, removing all records whose IDs are in the global selection set.

Hint (OutSystems): The solution uses a JavaScript Set to maintain the selected identifiers (IDs) independently of the screen's pagination or filtering actions.
