feat: integrate figlet-fonts statically and migrate to Coolify deployment

- Add 373 figlet fonts from xero/figlet-fonts as static assets
- Remove GitHub Actions workflow (now using Coolify + webhooks)
- Update .gitignore to track fonts in repository

This eliminates the need to clone fonts at build time and simplifies deployment.
