Drop redundant ProtocolParametersUpdate conversion in shelleyToBabbage update

`makeShelleyUpdateProposal` (cardano-api ^>=11.1) accepts
`EraBasedProtocolParametersUpdate era` directly. The existing code in
`shelleyToBabbageProtocolParametersUpdate` constructed that value,
converted it to the deprecated `ProtocolParametersUpdate` via
`createEraBasedProtocolParamUpdate` / `fromLedgerPParamsUpdate`, and
passed the result to `makeShelleyUpdateProposal` — an unnecessary
round-trip through the old API.

Drop the conversion; pass `eraBasedPParams` directly. No behaviour
change.

Drops the last remaining uses of the deprecated old-API transaction
body surface (`TxBody`, `getTxBody`, `getTxBodyAndWitnesses`,
`makeShelleyKeyWitness`, `makeSignedTransaction`,
`evaluateTransactionExecutionUnits` on a deprecated `TxBody`,
`getTxId . getTxBody`) from cardano-cli's source tree.

`IncompleteTxBody` is reworked from a `newtype` wrapping
`InAnyShelleyBasedEra TxBody` into a GADT existential carrying
`Exp.UnsignedTx (ShelleyLedgerEra era)` plus `IsShelleyBasedEra`
evidence. `readFileTxBody` pattern-matches `ShelleyTx _ ledgerTx`
directly and wraps as `Exp.UnsignedTx ledgerTx` — no `getTxBody`.

Consumers in `Transaction.Run` are migrated to:
- `makeShelleyKeyWitness'` (ledger-level body) and `addWitnesses` for
  signing — both non-deprecated and work for all Shelley-based eras,
  preserving pre-Conway support.
- `getTxIdShelley` for transaction IDs.
- `evaluateTransactionExecutionUnitsShelley` (operates on the ledger
  `Tx` directly) for `transaction calculate-plutus-script-cost`,
  preserving Alonzo+ era support.
- `Exp.evaluateTransactionFee` on `Exp.UnsignedTx` for
  `transaction calculate-min-fee` (already Conway+ via `sbeToEra`).

`TransactionView.Run` no longer needs the
`makeSignedTransaction []`-then-extract-ledger boundary that PR #1374
added — the new `readFileTxBody` returns `Exp.UnsignedTx` directly.

The TextEnvelope I/O boundary still uses `Tx era` and `ShelleyTx _`
(both non-deprecated), since `Exp.UnsignedTx`/`Exp.SignedTx` have no
`HasTextEnvelope` instance. The on-disk `.tx`/`.txbody` formats are
unchanged.

The compatible command path (`Cardano.CLI.Compatible.Transaction.Run`)
was already using non-deprecated symbols (`makeShelleyKeyWitness'`,
`addWitnesses`) and is unchanged by this commit.

`TxBodyFile` was a `File (TxBody ())` whose phantom payload was only
ever used as a file-tag for option/parser plumbing; the bytes on disk
do not depend on it. Replace `TxBody ()` with a fresh empty
`TxBodyTag` data type so the alias no longer references the deprecated
`TxBody` from cardano-api PR #1200.

No on-disk format change. No call-site change beyond the alias itself.

Pins cardano-api to the master commit containing PR #1200, which
deprecates `TxBody`, `TxBodyContent`, `getTxBody`, `getTxBodyContent`,
`createTransactionBody`, `defaultTxBodyContent`, and `BalancedTxBody`.

Lets this PR verify -Wdeprecations is clean against the deprecated
surface. Remove this stanza once cardano-api releases a version
containing #1200.

Migrate friendly transaction renderer to experimental API (Exp.Era era)

Migrates Cardano.CLI.Compatible.Json.Friendly off the old-API
Tx / TxBody / TxBodyContent onto Exp.SignedTx / Exp.UnsignedTx, with
the public renderer functions (friendlyTx, friendlyTxBody,
friendlyTxImpl, friendlyTxBodyImpl) now taking Exp.Era era instead of
ShelleyBasedEra era. This is the last consumer of old-API
TxBodyContent in cardano-cli.

Behaviour change: 'cardano-cli debug transaction view' and
'cardano-cli transaction view' now only accept Conway and Dijkstra
tx / tx-body files. Pre-Conway files (Shelley, Allegra, Mary, Alonzo,
Babbage) fail with a DeprecatedEra error. The corresponding pre-Conway
golden tests have been removed.

Added in the migration commit but no {..} patterns use it.

The previous commit bumped cabal.project's cardano-haskell-packages
index-state to 2026-05-08T13:26:45Z, but the nix-side CHaP pin in
flake.lock was still at 2026-04-30. haskell.nix-driven CI checks
(actionlint, check-formatting, check-cabal-files, check-cabal-gild,
test-hls-works, shellcheck) all failed with Cabal-7159 "Latest known
index-state for 'cardano-haskell-packages' (2026-04-30T13:08:25Z) is
older than the requested index-state (2026-05-08T13:26:45Z)".

Updated via `nix flake lock --update-input CHaP` per CONTRIBUTING.md.

cardano-api 11.1.0.0 is the first published release containing the
EraBasedProtocolParametersUpdate migration this branch depends on
(cardano-api PR #1103). Bump the CHaP index-state past its publication
and widen the cardano-cli library constraint from ^>=11.0 (which means
>=11.0 && <11.1 under PVP caret-equality) to ^>=11.1 so the solver
picks the new release.

Now that the friendly renderer covers Shelley through Babbage, those
tx bodies' update field is no longer just noise — it carries real
governance state (a ProposedPPUpdates map keyed by genesis-key hash and
an EpochNo). Render it directly from the ledger TxBody via
`updateTxBodyL`. Conway replaced update proposals with the new
governance system, so the field is absent (not null) in Conway+.

Adds `updateProposalPairFor` and `renderUpdate` helpers; the
per-era PParamsUpdate is rendered via its ledger ToJSON instance.

friendlyTx and friendlyTxBody now take ShelleyBasedEra era and accept
Exp.SignedTx era / Exp.UnsignedTx (ShelleyLedgerEra era). They are no
longer parameterised by Exp.Era era (which is Conway-only) — the
renderer works for Shelley through Conway tx and tx-body files,
unblocking transaction view for pre-Conway tx files.

friendlyTxBodyImpl reads every field directly from the ledger TxBody
via lenses, so the old API's TxBodyContent constructor and
getTxBodyContent are no longer used in this module.

The body composes a list of pairs from per-feature helpers
(validityRangePair, mintPairFor, collateralInputsPairFor,
requiredSignersPairFor, referenceInputsPairFor, totalCollateralPairFor,
returnCollateralPairFor, alonzoScriptWitnessPairsFor,
conwayBodyPairsFor). Era-gated helpers return [Aeson.Pair] and emit []
in eras that don't have the field, so JSON keys for absent-in-this-era
fields (e.g. "mint" in Shelley, "collateral inputs" in Mary) are
omitted from the output rather than rendered as null. The eon-based
dispatchers (forShelleyBasedEraInEon, AlonzoEraOnwards,
ConwayEraOnwards, ...) are no longer used in this module.

Also adds an Alonzo YAML golden test alongside the existing JSON
golden to cover the YAML output path for that era.

Relies on cardano-api 11.1.0.0 (PR IntersectMBO/cardano-api#1199),
which widened Exp.SignedTx / Exp.UnsignedTx to all Shelley-based eras.

The 7-way ShelleyBasedEra case duplicated body/mAuxData extraction and
a near-identical field list (with Null placeholders) in every branch.
Extract one helper per feature (validityRangePair, mintPair,
collateralInputsPair, requiredSignersPair, referenceInputsPair,
totalCollateralPair, returnCollateralPair) plus
alonzoScriptWitnessPairsFor / conwayBodyPairsFor. The top-level body
now extracts body/mAuxData once and composes a flat list of pairs.

No behaviour change: all golden outputs are unchanged.

The body dispatches on ShelleyBasedEra at the top level and each
branch renders its full body inline. Era-gated fields (mint,
collateral, reference inputs, governance actions, etc.) are present
only in branches whose era supports them. The eon-based dispatchers
(forShelleyBasedEraInEon, AlonzoEraOnwards, ConwayEraOnwards, ...) are
no longer used in this module.

Relies on cardano-api 11.1.0.0 (PR IntersectMBO/cardano-api#1199),
which widened Exp.SignedTx / Exp.UnsignedTx to all Shelley-based eras.

Bump CHaP index-state to pick up cardano-api 11.1.0.0, which contains
the widening of Exp.SignedTx to all Shelley-based eras (PR #1199) used
by the friendly rendering work in this branch.

The field was hardcoded to null across all eras since the
update-proposal handling was removed in #1372. Always-null fields
are noise; drop the key entirely and regenerate the goldens.
