Personal tools flow - focus action - a11y

[Wagner3UB]

Corrected the one way path through the personal tools container using assistive tech

issue: #5121

1. The "personal tools" button, when activated, moves focus to the first focusable element inside the newly opened panel.
2. After the focus is set, the screen reader announces the panel context: "Personal tools, menu opened".
3. Navigation is one-directional — the user tabs through the panel items without looping back.
4. When focus leaves the last item (onBlur), it is moved to the toolbar's expand/shrink button, and "Menu closed" is announced.
5. Simultaneously, the panel is closed and all related state is reset.
