Enhance API and Chat Actions with Improved Provider Handling

- Added logging to `getClientApi` for better debugging of provider input and standardized provider names.
- Updated `ChatActions` to handle lowercase provider IDs, converting them to TitleCase for consistency with the ServiceProvider enum.
- Implemented defaulting to OpenAI when provider ID is missing and added relevant logging for session updates.
- Enhanced logging in `useChatStore` to track API call preparations and provider configurations.
