Description

This PR introduces infinite scrolling to the ExtensibleTableComponent, enabling lazy data loading as users reach the bottom of the table.

Checklist

• I fully tested it as developer / designer and created unit / integration tests
• I documented it (or no need to document or I will create a separate documentation issue)

How to test it?

1. Setup

   • Navigate to any page using ExtensibleTableComponent.
   • Ensure selectable and data binding are configured as usual.

2. Infinite Scroll ON ([infiniteScroll]="true")

   • Table height should be set ([tableHeight] input)
   • Scroll down slowly until you reach the bottom:
     • ✅ When not loading, loadMore event is emitted once.
     • ✅ While isLoading = true, further scrolls must not trigger loadMore.
   • Confirm that [loadingIndicator] shows a spinner while loading.
   • Confirm that pagination is not available

3. Infinite Scroll OFF ([infiniteScroll]="false")

   • Table height should adjust automatically (auto).
   • Pagination must be available again
   • Trigger a new request (e.g., change filter, refresh list):
     • ✅ The table should re-render correctly once new data arrives.

Closes #23671
