test(schema): add deserialization tests for empty and boolean schemas

Add theory tests across OpenAPI 3.1 and 3.2 to validate deserialization of: - Empty schema object ({}) - Boolean schema value (true) These tests ensure that non-standard but valid schema forms are parsed without errors and produce valid OpenApiSchema objects.
