test: pin the dev tunnel row in the TUI system panel

Browse Source 
Covers the render both ways: the Tunnel row appears with its URL when a
tunnel is published, and is absent for an ordinary `fn dashboard` run.
Verified by mutation — deleting the row from app.tsx fails the first test.

Driving this through a real TTY proved impractical from a non-interactive
shell (isTTYAvailable needs stdin AND stdout to be TTYs, which neither
`docker exec -t` nor a detached `script` provides), so the render is pinned
here instead of by observation.

FNXC:DevTunnel 2026-08-19-04:30:
`pnpm dev --tunnel` prints its banner to stdout, but a TTY run hands the screen to this TUI, which
repaints over it — the public URL, the whole output of the flag, was unreadable. The wrapper now
forwards it over IPC and it belongs in the system panel beside URL and Token.
