fix(infra): definitive fix for Traefik Host rule and Gatekeeper bypass

- Switched Traefik Host rules from backticks to double quotes for safety.
- Used printf in deploy.yml to guarantee literal writing of environment variables.
- Verified that Host rules now correctly match without shell-side side-effects.
- Maintained WOFF fonts for Satori compatibility.
