Cardano Updates

Replace genericToJSON and anyclass derivation with ShowOf-based instances
for ShelleyLedgerPredFailure, ShelleyUtxowPredFailure, AlonzoUtxowPredFailure,
and BabbageUtxowPredFailure. NonEmptySet lacks ToJSON, breaking genericToJSON.

A generic type to hold proof of inclusion for "v2" transactions and
blocks.

The errorFail import was removed in a previous commit when replacing
mkCostModelsLenient usage with mkCostModel. FailT is still used in tests.

- Genesis/Internal.hs: remove unused imports (errorFail, IsList); fix
  ppTxFeePerByteL type (CoinPerByte not Coin); use ppTxFeeFixedL (not deprecated)
- ChainSync/Client.hs: import chainSyncPeerNull from Cardano.Network.NodeToClient
- Reexport.hs: remove duplicate 'pattern PoolParams' export (covered by StakePoolParams(..));
  fix ChainAccountState import/export (no constructors, remove ..)

When a connection fails before any pong responses arrive, the JSON
logger would output the malformed fragment "] }" instead of valid JSON.
Now it outputs an empty result object (e.g. { "pongs": [] }) so that
callers parsing the output get well-formed JSON in all cases.

Fixes IntersectMBO/cardano-cli#1210

- Ed25519Bip32: rename DSIGNAlgorithm type families to non-deprecated names
  (SizeVerKeyDSIGN→VerKeySizeDSIGN, SizeSignKeyDSIGN→SignKeySizeDSIGN, SizeSigDSIGN→SigSizeDSIGN)
- Reexport: fix RewardAccount (pattern synonym), remove hashAnchorData (deleted),
  move hashVerKeyVRF to Cardano.Protocol.Crypto, fix PoolParams→StakePoolParams
- Network IPC: migrate Ouroboros.Network.NodeToClient→Cardano.Network.NodeToClient
  from cardano-diffusion package (3 files)
- Genesis: fix AlonzoGenesis fields (agCostModels→agPlutusV1CostModel+agExtraConfig)
- Orphans/Misc: fix PParams Semigroup instances (MinFeeA/B→TxFeePerByte/TxFeeFixed)
  for ShelleyPParams, AlonzoPParams, BabbagePParams, ConwayPParams
- cardano-api.cabal: add cardano-diffusion and cardano-diffusion:api dependencies
