fix: resize wireframe animation on Wayland (overlay flush per draw) 

The overlay drawing functions (wl_overlay_draw_rect, wl_overlay_draw_line) write XOR pixels to a client-side pixman buffer but never flushed it to the scene graph. On X11, each XDrawRectangle is immediately processed server-side, so the wireframe appears in real-time. On Wayland, the overlay buffer was only flushed in wl_server_ungrab() at the END of the resize operation. Added overlay_flush() after each draw call so each XOR batch is pushed to wlr_scene_buf and rendered immediately.
