In v2, JumpStart models deployed with EnableNetworkIsolation=True because the JumpStartModel class read inference_enable_network_isolation from the model spec JSON. In v3's ModelBuilder, this field was never extracted from the JumpStart init_kwargs or deploy_kwargs, causing all JumpStart models to deploy without network isolation (defaulting to False). This fix applies enable_network_isolation from the JumpStart model spec in both code paths: 1. _build_for_jumpstart() - regular build path via get_init_kwargs() 2. from_jumpstart_config() - classmethod path via _retrieve_model_deploy_kwargs() The user-provided value (via network= param) takes precedence.
Tests both code paths: 1. _build_for_jumpstart() - verifies enable_network_isolation is applied from init_kwargs and that user-set values are not overridden 2. from_jumpstart_config() - verifies enable_network_isolation is extracted from deploy_kwargs

…xture The mock directly inherits _ModelBuilderServers without going through ModelBuilder.__post_init__ which initializes this attribute.

Integration test builds a real SageMaker Model (falcon-7b) and verifies EnableNetworkIsolation=True via describe_model API. No endpoint deployed. Also adds _enable_network_isolation to MockModelBuilderServers fixture to fix 7 pre-existing unit test failures.

Issue #, if available:
Description of changes:
v3's ModelBuilder never applies inference_enable_network_isolation from JumpStart model spec metadata, causing all JumpStart models to deploy without network isolation (defaults to False). In v2, JumpStartModel read this from the spec and passed it to create_model().
