Bump cardano-api to 11.0.0.0

Adapt to the new `Either MakeUnsignedTxError (UnsignedTx ...)` return of
`Exp.makeUnsignedTx` (IntersectMBO/cardano-api#1181). Add a
TxCmdMakeUnsignedTxError constructor to TxCmdError so the error surfaces
with the existing fromEitherCli/firstExceptT idioms, and update the two
call sites in EraBased.Transaction.Run.

Bump the cardano-haskell-packages index-state and refresh the CHaP nix
flake input to pick up cardano-api 11.0.0.0
(IntersectMBO/cardano-haskell-packages#1358).
