Cardano Updates

Replace the deprecated getTxBody/getTxId chain in
Cardano.Rpc.Server.Internal.UtxoRpc.Submit with a direct ledger projection:
pattern-match the API Tx, then compute the TxId via Cardano.Ledger.Core.txIdTx
(which is bodyTxL composed with txIdTxBody) and lift back through
fromShelleyTxId.

Deprecates the old-API transaction body surface (the type, its
constructor, and direct producers/consumers) so users are pointed at
'Cardano.Api.Experimental'. Internal modules that still use these
symbols are annotated with -Wno-deprecations to keep -Werror green;
they will be migrated in a follow-up along with the setter family.

Deprecations:
- TxBody (data type), ShelleyTxBody (constructor)
- TxBodyContent (type/constructor)
- createTransactionBody, defaultTxBodyContent
- getTxBody, getTxBodyContent
- BalancedTxBody

The existing pattern-synonym TxBody deprecation message is updated for
consistency with the new messages.

Add regression test: makeUnsignedTx errors without protocol params for Plutus scripts

Release cardano-api 11.1.0.0

Widen Exp.SignedTx to all Shelley-based eras

Reparameterise Cardano.Api.Experimental.SignedTx and its
SerialiseAsRawBytes instance on ShelleyLedgerEra era instead of
LedgerEra era. This lets SignedTx and its raw-bytes deserialisation
type for every Shelley-based era (Shelley through Dijkstra) without
widening the LedgerEra family or its Conway-onwards constraint
surface (EraCommonConstraints), which would have rippled into the
experimental tx builders.

Build paths (signTx, makeKeyWitness, convertTxBodyToUnsignedTx) take
Era era, whose constructors only cover Conway/Dijkstra, so they
remain Conway+ gated; for those eras LedgerEra era ~ ShelleyLedgerEra
era is provided by obtainCommonConstraints, so the SignedTx
constructor application elaborates with no further changes.

The motivation is unblocking cardano-cli's debug transaction view,
which handles InAnyShelleyBasedEra and needs to deserialise into
Exp.SignedTx era for pre-Conway tx files.
