🐛 Bug: "Apply Filters" button is buried at the bottom of long dropdown lists

Describe the bug

• When opening a long dropdown menu in the "Tools" or "Specification" section (e.g., the "License" filter), the "Apply Filters" and "Clear Filters" buttons are not visible immediately. The user must scroll to the very bottom of the selection list to find the action buttons, which creates a poor user experience.

Steps To Reproduce

1. Go to the JSON Schema Tooling page.

2. Slightly scroll down and then click on a filter with many options, such as License. (scroll up and down few times or select any filter)

3. Observe that the "Apply Filters" button is missing from the initial view.

4. Scroll to the bottom of the list to see the button.

Expected Behavior

The filter action buttons ("Apply Filters" and "Clear Filters") should be sticky or fixed at the bottom of the dropdown container so they are always visible, regardless of how many items are in the list.
