cardano-node: remove iohk-monitoring tracing backend

feat: ledger peers support for DMQ node

amaru-relay-1/2 peered directly with producers p1/p2. Point them at relay1/relay2
instead: these relays are in the fault-exclusion set, so the system-under-test
syncs from a stable upstream while only the amaru relays take faults. Add a
depends_on so each amaru waits for its relay to start.

epoch_length=256 kept the stability window inside an epoch but pushed the
2-epochs-behind-immutable bootstrap to ~slot 900 (~15 min), past the Antithesis
setup-time budget, so runs aborted incomplete before amaru ever started.

k=5, f=0.2 gives windows 75 (3k/f) and 100 (4k/f), both < epoch_length=120, so
rewards still stabilise in-epoch, and the bootstrap reaches its 2-epochs-behind
point by ~slot 360 (~6 min). Applied consistently across testnet.yaml,
amaru-runtime/global-parameters.json and amaru-runtime/era-history.json.
