Cardano Updates

The previous version required a separate `bumpalo::Bump` alongside the
`Arena` to construct slices, because amaru-uplc's `Arena` only exposes
`alloc<T>` / `alloc_integer`.

Match the upstream amaru node's pattern: CBOR-encode the pallas
`PlutusData` and call `PragmaPlutusData::from_cbor(&arena, &bytes)`. The
decoder allocates slices and integers into the arena internally, so we
no longer need a parallel Bump or the `num-bigint` dep, and the manual
`map_pallas_data_to_pragma_data` recursion goes away.

Use the official `amaru-uplc` crate from pragma-org/uplc instead of the
`pallas-uplc` fork on crates.io (published from txpipe/uplc-turbo).

API differences required:
- evaluator allocations now use `amaru_uplc::arena::Arena`; a separate
  `bumpalo::Bump` is kept for slice allocations since `Arena` only exposes
  `alloc<T>` / `alloc_integer`
- `Integer = num::BigInt`, so `integer_from_bytes_and_sign` is replaced
  with `arena.alloc_integer(BigInt::from_bytes_be(sign, ..))`
- `flat::decode` now requires `PlutusVersion` and `protocol_version_major`,
  threaded through `eval_tx` -> `eval_redeemer` -> `execute_script`
- `program.eval` is replaced with `program.eval_version` so each script
  runs with its own Plutus version semantics

It was using block slots of all nodes and failed when we had one block
certifying, e.g.: certifyingSlots = [91, 91, 91]

This adds an assertion that (slots of) chains are consistent and either
the gap is correct or only a single block certifies.

Reduce STM contention in V2 TxSubmission inbound by splitting per-peer
in-flight bookkeeping out of SharedTxState into a small per-peer
PeerTxInFlight TVar. SharedTxState is now only written when the shared
state updates. The common case of a new peer advertising an existing
txid is just a read operation for the shared state and a write operation
into the peer local TVar.
