wayland: Phase 44 — client_synth_configure/window_resize send XDG configure 

Implement three vtable slots:
  - client_synth_configure: calls wlr_xdg_toplevel_set_size + schedule_configure
    so the WM can resize/reposition XDG toplevel clients
  - window_resize: same — sends a configure with the new width/height
  - window_move: no-op comment (position is WM-side only for Wayland)

All three use wl_find_view_by_id to recover the wl_toplevel_view.
