fix: taskbar pins, Edge NTP, black bg, step progress strip

- 04-default-profile: default profile now pins Explorer+Edge (was empty),
  preventing MS Store and other defaults from appearing in taskbar
- 03-system-registry: disable Edge new tab page quick links, background,
  content feed (NewTabPageQuickLinksEnabled/BackgroundEnabled/AllowedBackgroundTypes)
- 05-personalization: set Wallpaper="" in default hive so new user accounts
  get solid-color background instead of black fallback
- runner: add onStepStart callback, fires before each script launch
- gui: step progress strip in run phase — color-coded labels per step
  (pending gray · / running blue ► / ok green ✓ / error red ✗ / skipped gray –)
