feat: Add comprehensive GPT-5 support with Responses API integration

- Add GPT-5 model definitions (gpt-5, gpt-5-mini, gpt-5-nano, gpt-5-chat-latest)
- Implement GPT-5 Responses API support with intelligent fallback to Chat Completions
- Add GPT-5 specific parameter handling (max_completion_tokens, temperature=1)
- Support custom tools and freeform function calling capabilities
- Add reasoning effort and verbosity control parameters
- Implement GPT-5 connection testing service
- Add model capability detection and automatic parameter transformation
- Support both official OpenAI and third-party GPT-5 providers
- Add todo list and sticker request UI components
- Improve notebook support with better type definitions
- Enhance debug logging and error handling for GPT-5
- Update model selector with GPT-5 compatibility checks

This commit provides full GPT-5 support while maintaining backward compatibility with existing models.
