fix(install): use gateway service instead of foreground run, add completion hints (#1406)

## Summary

- **Replace foreground `gateway run` with background service**: Use
`openclaw gateway install` + `openclaw gateway start` instead of `exec
npx openclaw gateway run`. The gateway now runs as a system background
service (launchd/systemd/schtasks), so the install script exits cleanly
and Ctrl+C won't kill the gateway.
- **Add post-install hints**: Show the user OpenClaw Web UI
(`http://localhost:<port>`) and Memory Viewer (`http://localhost:18799`)
URLs after installation completes.

## Files changed

- `apps/memos-local-openclaw/install.sh`
- `apps/memos-local-openclaw/install.ps1`

## Test plan

- [ ] Run `bash install.sh --version <version>` — verify script exits
after installation
- [ ] Verify gateway is running as a background service after script
exits
- [ ] Verify Web UI and Memory Viewer URLs are displayed at the end
- [ ] Ctrl+C during the install process does not leave gateway in a
broken state
