Subject: [PATCH] fix: combine gateway start + port wait into single SSH
 session (#1642)

The old flow opened up to 60+ separate fly ssh console sessions to
poll port 18789 after starting the gateway daemon. Each session opens
a new WireGuard tunnel which is slow and flaky.

Now: one SSH session starts the daemon, then polls the port in-band
with a simple for loop. Output from the loop also serves as a
keepalive for flyctl.
