Cardano Updates

Fault only the system-under-test (amaru-relay-1/2). Antithesis was killing the
single-shot bootstrap-producer and p1 mid-bootstrap, so amaru never started and
runs aborted incomplete. com.antithesis.exclude_from_faults labels keep the
chain, bootstrap, and observability up; moog emits the custom.*_exclusion launch
params from them.

cardonnay's config left TraceOptions empty, so UseTraceDispatcher emitted
everything at Info (~43M events). Antithesis could not materialise that
volume (the 'very high output' Never property) and the sidecar's
log-presence assertions (Any p1/p2 log, cluster fork observed,
SwitchedToAFork, PeerStatusChanged, find log files) were starved.

Apply the master testnet's per-namespace severity discipline plus silence
ChainDB.ImmDbEvent chunk-validation replay spam. Governance invariants
already pass; this clears the trace-firehose cascade so the run reaches
baseline parity.
