A11y Bug 8780715 : add keyboard focus to success panel and region selecting panel

[KethanaReddy7]

Add automatic focus management to ensure keyboard focus is visible when the success panel and region selecting panel are first rendered. This addresses accessibility issue MAS 2.4.7 (Focus Visible).

• Add initiallySetFocus method to SuccessPanelClass
• Add onElementFirstDraw to focus "View in OneNote" button on success
• Add initiallySetFocus method to RegionSelectingPanelClass
• Add onElementFirstDraw to focus "Back to Home" button in region panel

Fixes #628
