Fixed - Improved accessibility and keyboard usability for request logs provider/model details in the WordPress admin

What?

Closes #

This PR improves the accessibility and keyboard usability of the request logs provider/model details UI in the WordPress admin.

Why?

The previous interaction used a non-semantic clickable container, which made the control harder to use with assistive technologies and keyboard navigation. This change improves usability for screen-reader and keyboard users and makes the popover behavior clearer.

How?

The provider/model details control was updated to expose better ARIA state information, improve keyboard handling for Enter, Space, and Escape, and add a visible focus indicator for keyboard users. The UI remains functionally the same, but the interaction is more accessible and predictable.

AI assistance: No

Testing Instructions

• Open the WordPress admin request logs view.
• Verify that the provider/model details control can be opened and dismissed with mouse and keyboard.
• Confirm that keyboard focus is visibly indicated when tabbing to the control.
• Check that the control announces its expanded/collapsed state appropriately with assistive technology.

At a quick review this looks fine to me but noting there are JS lint errors that will need resolved before this can be reviewed further
