- OpenAI API key moved fully server-side.
- Removed the API-key box and Test Key button from the web editor.
- Browser no longer stores or sends an OpenAI key.
- openai-proxy.php now authenticates to OpenAI using openai-secret.php.
- Added Apache protection preventing direct web access to openai-secret.php.
