🔑 fix: Gemini Custom Endpoint Auth. for OAI-Compatible API (#10806)

Browse source 
* 🔧 fix: Gemini as Custom Endpoint Auth. Error for OAI-compatible API

* refactor: Google Compatibility in OpenAI Config

- Added a test to ensure `googleSearch` is filtered out when `web_search` is only present in `modelOptions`, not in `addParams` or `defaultParams`.
- Updated `transformToOpenAIConfig` to preserve `googleSearch` tools if `web_search` is explicitly enabled via `addParams` or `defaultParams`.
- Refactored the filtering logic for Google-specific tools to accommodate the new behavior.
