Update nginx configuration with SSL and WebDAV support

- Add SSL certificate configuration from Let's Encrypt
- Include WebDAV headers for copyparty upload support (Depth, Destination, Overwrite, If)
- Configure HTTP to HTTPS redirect for all services
- Add SSL security settings managed by certbot
- Enable proxy_request_buffering off for WebDAV compatibility
