Merge PR #41: default gluecron port 3001 to avoid Crontech conflict

fix(deploy): default port 3001 (Crontech owns 3000)</title>
<parameter name="body">Root cause of the 5810-restart crash-loop on gluecron.com. The bare-metal box hosts both Crontech and Gluecron; Crontech's web server binds port 3000 since Apr 29, but the gluecron deploy script also defaulted to 3000. EADDRINUSE on every gluecron restart.

Fix: default PORT=3001 in deploy-crontech.sh. Caddy still routes gluecron.com to whatever port /etc/gluecron.env specifies.

The owner ran the SSH one-liner already to move the live box to 3001 — this commit just updates the script default so future fresh box deploys don't recreate the conflict.</parameter>
