Cardano Updates

Remove the "genesis spec" workbench command that was used for `create-testnet-data --spec-*` and instead use what cardano-profile provides.

The profile may have null "conway" or "dijkstra" genesis fields but the node still needs valid files, use a "zero" genesis in those cases.

Based on a mainnet db-sync and mainnet genesis files we reconstructed the timeline with no cardano-profile implementation specifics

Going forward, the only way to inject cost models with any number of parameters is through Alonzo genesis "extraConfig" field.

- Structure: Separates cost models from the rest of the parameters.
- Consistency: Shelley genesis is the full object, no only the "protocolParams" field.
- Consistency: Uses everywhere an object for the cost model, no arrays.
- Cost model names are updated.

Were removed when the node started only considering valid what mainnet shipped with

The pool relays were wrote into the Shelley genesis (via `pool-relays.json` and `cardano-cli ... --relays` / `--relay-specification-file`) are only consumed by ledger-peer discovery.

With ledger peers off and `publicRoots` empty, the relay records in genesis are never read.

Every workbench topology disables it:
- the supervisor (local / 127.0.0.1) backend gets `useLedgerAfterSlot: -1` from `cardano-topology projection-for`.
- the Nomad backend hardcodes the same value (nix/workbench/backend/nomad-job.nix).

Was converging to `create-staked` output, keep `create-testnet-data` layout:
- pools-keys/poolN/{cold,kes,vrf,opcert}.{skey,vkey,cert,counter}
- stake-delegators/delegatorN/{payment,staking}.{skey,vkey}
- drep-keys/drepN/drep.{skey,vkey}
- utxo-keys/utxoN/utxo.{skey,vkey}
- genesis-keys/genesisN/key.{skey,vkey}
- delegate-keys/delegateN/{key,kes,vrf,opcert}.{skey,vkey,cert,counter}
- byron-gen-command/

Normalises genesis files names. Every era's genesis file is now genesis.<era>.json everywhere:
- genesis.byron.json
- genesis.shelley.json
- genesis.alonzo.json
- genesis.conway.json
- genesis.dijkstra.json

Details:
- create-testnet-data drops its symlink-creation block and the `link_keys` helper (no longer needed under the native layout).
- Removes `Massage_the_key_file_layout_to_match_AWS`, `key_depl` and `key_genesis`.

Genesis file names are unchanged here.

cardano-node: remove iohk-monitoring tracing backend

This allows us to easily identify that this is a leios prototype
version. The <major>.<minor>.<patch> is the version on which release the
prototype is based on, while the .164 suffix is directly supported by
the Haskell version parsing and references CIP-164
