apollo_deployments: introduce hybrid layout for infra config

[nimrod-starkware]

Pure-data hybrid layout descriptor (6 services) transcribed from hybrid.rs and
the hybrid overlay service YAMLs, plus the infra-only service renderer that maps
each service through derive.componentsFor.

PR Summary

Low Risk
Additive jsonnet configuration only; no changes to runtime deployment or Rust hybrid logic.

Overview
Adds a hybrid deployment layout to the jsonnet infra pipeline as pure data plus a thin generator entrypoint.

hybrid.libsonnet defines the six-service topology (committer, core, gateway, l1, mempool, sierra_compiler): which components each service runs vs uses remotely, DNS names, shared ports, idle/retry tuning, and catalog-backed reactive/active lists—including local-only reactive components (config_manager, mempool_p2p). The structure is documented as transcribed from hybrid.rs / hybrid overlay YAMLs.

services/hybrid.jsonnet loops over hybrid.services and calls derive.infraFor so each service gets a full components map from the shared derive logic (same pattern as other layouts under lib/layouts/).
