deployment: add native config layers for the testing overlays

[nimrod-starkware]

Under the native config path an overlay's config comes from sequencer_config.jsonnet
layers (YAML sequencerConfig is ignored). The testing/node-0 and testing/all-constructs
overlays (synthed by the cdk8s-test and hybrid-system-test CI jobs) had no native layer,
so native synth aborted on unconditionally-read overrides.* keys (validator_id, the outer
committer cache_size, ...).

• testing/node-0: full value-parity native layer (the folded translation of its combined
  YAML sequencerConfig). It is deployed live by hybrid_system_test, so values are
  load-bearing; guarded by a strict mirror test (test_node0_layer_jsonnet_mirrors_combined_yaml).
• testing/all-constructs: a structure-validation stub supplying exactly the unconditional
  overrides.* reads the base layer does not provide, with clearly-dummy immaterial values
  (its synth is only kubectl-validated for manifest structure); guarded by a synth-success
  test (test_all_constructs_native_config_synthesizes).

This lets every CI-synthed overlay build under native, before the default flip.

PR Summary

Low Risk
Changes are limited to test/CI overlay config and a unit test; no sequencer runtime or auth logic is modified.

Overview
Adds native hybrid overlay jsonnet (chain_params, node_params, replacers) for testing/all-constructs and testing/node-0 so cdk8s can synthesize under --config-format native without failing on required overrides.* keys (e.g. validator_id, committer cache).

testing/all-constructs uses clearly dummy values—only enough for native synth and manifest structure validation in CI. testing/node-0 carries real integration-style chain settings (Sepolia URL, BPO block numbers, fee tokens, batcher/consensus/gateway deltas) aligned with the overlay used by hybrid system tests.

test_native_config.py now asserts build_native_config succeeds for hybrid.testing.all-constructs and returns a non-empty nested dict.

Missing P2P sync replacer entry

High Severity

The testing/node-0 native replacers set state_sync_config.static_config.central_sync_client_config to null and configure P2P network_config, but omit a replacer to enable p2p_sync_client_config. The overlay YAML explicitly turns P2P sync on, so native synthesis leaves both sync clients disabled and breaks the load-bearing hybrid test layout once native config is used.
