Cardano Updates

- Tighten output file perms in gen-rollback-vector from 0o644 to 0o600
  to satisfy gosec G306 (was the only failing lint check on the PR).
- Treat conformance/testdata/eras as required in collectAllVectors;
  only synthetic/ may be absent. A missing eras/ now returns an error
  instead of silently producing an empty vector run.
- Strengthen TestHarnessRollbackReappliesRewardBalances to seed an
  originalIdx that differs from the replay-loop index, so the test
  actually proves the journaled index drives the lookup rather than
  passing accidentally when the two indices coincide.

None of these were produced anywhere in the repo — only defined,
pretty-printed, and listed in golden fixtures.

Removed:
  - TransactionValidityError (entire type, both constructors:
    TransactionValidityIntervalError, TransactionValidityCostModelError)
  - TxFeeEstimationTransactionTranslationError, the TxFeeEstimationError
    constructor that wrapped TransactionValidityError
  - TxBodyErrorByronEraNotSupported, TxBodyErrorMissingParamMinUTxO, and
    TxBodyErrorNonAdaAssetsUnbalanced from the legacy
    Cardano.Api.Tx.Internal.Fee.TxBodyErrorAutoBalance
  - TxBodyErrorNonAdaAssetsUnbalanced from the experimental
    Cardano.Api.Experimental.Tx.Internal.Fee.TxBodyErrorAutoBalance

The corresponding test_TransactionValidityError golden test, the three
dead TxBodyErrorAutoBalance fixture entries, and their expected .txt
files are dropped too. The Ouroboros.Consensus.HardFork.History import
in Fee.hs becomes unused and is removed.

Pulls in 497122fc9 ("Fix Werror warnings in NodeKernel after late-join
changes"), which resolves -Wname-shadowing build failures in
ouroboros-consensus-diffusion.

Drop unused Data.Set and EbHash imports, and rename the shadowing
'handle' binding to 'csHandle' in the candidateCertEbs computation.
