fix: configure asciinema SMTP with EMAIL_FROM and disable signup

- Add EMAIL_FROM to arty.yml environment defaults
- Configure asciinema to use EMAIL_FROM for MAIL_FROM_ADDRESS
- Set SMTP_SSL to true for IONOS SMTP on port 465
- Set SIGN_UP_DISABLED default to false (will enable after admin creation)
- Follow netdata compose.yaml pattern for Traefik labels
- Add proper HTTP to HTTPS redirect middlewares
- Configure compression and security headers
