apollo_node_config,apollo_config_manager,apollo_integration_tests: retire preset config-generation path

[nimrod-starkware]

Delete the flat-preset config generation now that everything loads native: remove
ConfigPointersMap and DeploymentBaseAppConfig::{as_value, dump_config_file,
config_pointers_map, get/modify_config_pointers, validate_all_pointer_targets_set}.
Migrate the integration-test setup and config_manager_runner_tests off the pointer-
resolved as_value path to the native as_native_value path (the config_manager test was
already failing at HEAD: it passed a single --config_file but native load requires two).
Promote normalize_pointer_groups to a shared cfg(testing/test) helper in config_utils.
create_node_config now sets validator_id directly on the real struct (the native dump
ignored the pointer map).

This unblocks deleting CONFIG_POINTERS (its only remaining consumers are the secrets-schema
bin + the transient equivalence test). apollo_config_manager 15/15, apollo_node_config
34/34, apollo_deployments 8/8 green; integration bins compile.
