fix: resolve recursion in OVHCloud get_supported_openai_params (#24118)

* fix: resolve recursion in OVHCloud get_supported_openai_params (#24111)

Root cause: OVHCloudChatConfig.get_supported_openai_params() called
get_model_info() which called back into get_supported_openai_params(),
causing infinite recursion and falling back to no tools support.

Made-with: Cursor

* fix: use .get() for TypedDict + don't hardcode function_calling support

Made-with: Cursor
