fix(desktop): external gateway mode and start script alignment

- Add desktop env for non-embedded gateway (OCLAW_DESKTOP_EMBED_BACKEND, base URL, skip channel).
- Wire start_all/start_desktop to pass gateway URL when keeping existing gateway; fix root start_all flags.
- Prefer electron.cmd for background desktop launch; admin static theme presets and chat boot timeouts.
