fix: 🐛 Force port 80 in Caddyfile

- Add port 80 to the server address
- Add trailing newline to the Caddyfile
- Fix extra whitespace in the `Cache-Control` header

These changes ensure that Caddy listens on the correct port and prevent potential parsing issues due to the missing newline.  The whitespace fix improves consistency and readability.
