Cardano Updates

Remove 4 file-level eslint-disable directives and fix each type violation with proper type annotations and runtime validation:

- Replace any with unknown in method signatures for type safety
- Use Record<string, unknown> casts at data boundary points
- Add runtime type narrowing (typeof checks, instanceof checks)
- Use inline as type assertions where values originate from external APIs (credential.id, credential.issuer, etc.)
- Fix catch block error handling: use err instanceof Error instead of (err as Error).message pattern
- Fix SDJWT issuer type: convert string to DID via DID.fromString()
- Fix template literal type errors with explicit string casts

- Separates cost models from the rest of the parameters
- Uses an object for the cost model instead of an array

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

spec-jq gets a dijkstra) case sourcing the zero preset's dijkstra-genesis.json; spec-modular falls back to jq for dijkstra since the Nix modules don't cover it yet

The pool relays we 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.

Replaces 'cardano-cli byron genesis genesis'.

Removes genesis-byron-{jq,modular} and the genesis-byron dispatcher.

Default is `create-testnet-data`

Function `derive-from-cache` becomes a backend implementation.

Both `derive-from-cache` and `finalise-cache-entry` are merged and inlined into `derive-from-cache-jq` (`derive-from-cache-modular` delegates to "jq").

  Merge the two-callback interface (mkTx + fitsCheck) into one
  (Int -> m (Maybe tx)) where Nothing means doesn't fit and Just tx
  means fits. This enforces at the type level that construction and
  checking always happen together.

  Also rename mkTxM to buildTx in findFittingFanoutTx's where bindings.
