Fix remaining sky* references missed in Phase 7 rename

- Dockerfile: WORKDIR /skyos → /orionos, ENTRYPOINT path, image name
- Makefile: skyos-default.png → orionos-default.png in install target
- iso/build-base.sh: all sky*/SkyOS → orion*/OrionOS
- iso/mac-install-notes.md: update install instructions for OrionOS
- themes/OrionOS: finish renaming sky* strings in gtkrc, gtk.css, index.theme
