Add desktop switcher and task context menus

Show numbered desktop indicator buttons between the nav buttons and
the keyboard toggle corner button. Each button highlights the current
desktop and switches on click via VirtualDesktopInfo.requestActivate.
Only visible in convergence mode when multiple desktops exist.

Add Minimize and Maximize/Restore actions to the task strip
right-click context menu alongside the existing Close action.
