feat(maestro): port kill dialog, help overlay, context menu, drawer to React

Closes #250: kill confirmation/force-kill (dialogs/KillDialog), the ? shortcuts overlay (dialogs/HelpOverlay), the general-purpose right-click menu (common/ContextMenu, closes on scroll/resize unlike the sidebar's own), the mobile drawer with swipe support (layout/Drawer), and the visual-viewport hook (hooks/useViewport). Each is a standalone, tested port of its vanilla-DOM source; wiring into the shell is a later issue.
