Fix screen init: create RContext + WINGs screen on XWayland in Wayland mode

- wScreenInit Wayland fast path now creates RContext on XWayland display
  (needed for wTextureRenderImage and wraster image loading)
- Also creates WINGs screen (wmscreen) so WMDrawString/WMFontHeight work
- Add wl_get_x_display() accessor for screen.c to get XWayland Display*
- Remove if(dpy) guard around wScreenRestoreState in startup.c so dock,
  clip, menus, and window management run in Wayland mode

Status: startup reaches menu creation but hangs in wMenuCreate due to
Xlib operations on XWayland during WINGs font/screen init. The pump
thread is running but something in the menu creation path is spinning.
Next step: identify and eliminate the remaining XWayland dependency in
the menu creation path.
