Revert to working nginx panel configuration

- Back to proven rewrite + break pattern that was working
- Keep the added proxy headers for proper forwarding
- Remove the trailing slash approach that broke functionality

Working pattern:
- rewrite ^/panel/(.*)$ / break strips /panel/ prefix
- proxy_pass http://127.0.0.1:9002 (no trailing slash)
- Restores https://afrihornet.ngrok.io/panel/ functionality
