Partnership phase 0: terminal link + clickable command block

At phase 0, show below the buttons:
- 'Open Terminal' link using HOST1's Tailscale IP (/webterminal/ttyd/)
- Clickable command code block (click to copy) with the Phase 1 script path
- Note that tab auto-updates on next poll when the script completes

Tailscale IP comes from selfNode.ts_ip already in the API response.
