feat: Integrate OpenRouter API and update AI model

Migrate AI API endpoint from local server to OpenRouter.
Update the default AI model to `google/gemini-2.5-flash-preview` for improved performance and capabilities.
Add authorization header for OpenRouter API calls.
Introduce a new cog `roleplay_teto_cog.py` (untracked) for potential future roleplay features.
