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

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.
