deployment,ci: add hybrid native override layers and their validation tests

[nimrod-starkware]

Add the base (common) and sepolia-integration sequencer_config.jsonnet override
layers consumed by the native config builder, plus the tests that validate them:
the AUTHORITATIVE PARITY test (native build vs folded/filtered preset across
hundreds of applicative keys) with its negative gate, the "jsonnet mirrors combined
YAML" layer tests, and the cross-repo overlay collision / disjoint-leaf-key guards.
The devops-dependent tests skip cleanly when the devops overlay checkout is absent
(as in CI). Run the full test/ pytest suite in the cdk8s CI workflow instead of
only the port-uniqueness test, so these gate in CI.

PR Summary

Low Risk
Additive integration-environment deployment config guarded by an existing parity test pattern; no runtime code paths change in this diff.

Overview
Adds the hybrid sepolia-integration native override sequencer_config.jsonnet, so the nested config builder can apply the same integration-specific sequencer settings as the YAML overlays (chain/feeder URLs, L1 block anchors, batcher limits, consensus committee defaults, gateway bucket, state sync, etc.).

Extends the native config lockstep regression from the common layer only to every overlay layer: docs/comments now describe per-layer parity, and test_integration_layer_jsonnet_mirrors_combined_yaml asserts the new jsonnet matches the folded combined config.sequencerConfig from that layer’s YAMLs.
