Cardano Updates

Move registry wrapping ahead of event bus construction so that
event bus metrics also receive the network label. Previously the
event bus was created with the unwrapped registry.

Wrap the prometheus registry with a constant "network" label after
the network magic is resolved. Every metric registered by subsystems
automatically carries network="mainnet" (or preview, preprod, etc.)
with zero changes to individual metric definitions.

If the network was configured by name, that name is used directly.
If only the magic number was provided, the name is resolved via
ouroboros.NetworkByNetworkMagic().

Fix serialiseToCBOR to extract raw script bytes from PlutusRunnable
instead of using L.serialize' which adds CBOR framing that
deserialiseFromCBOR does not expect.

Add CBOR and TextEnvelope roundtrip tests for PlutusScriptInEra and
AnyPlutusScript. Add haddocks for the text envelope functions.

Use nonNativeLanguages and withSLanguage to derive textEnvTypes
so new Plutus versions are picked up automatically and GHC
enforces handling in constraint witness functions.

  singlePartyHeadFullLifeCycle now exercises the deposit (commit) flow
  using timing-derived deposit period instead of a hardcoded value, so the
  deposit activates within the test timeout on both devnet and real networks.

  waitForNodesSynced now waits for the Greetings message before declaring
  the node ready. Greetings is always sent after the full historical event
  replay, making it a reliable separator between replayed and live messages.
  This prevents tests from matching on historical HeadIsOpen or NodeSynced
  events from a previous run's persisted state — which caused the smoke test
  to proceed with a stale headId and then fail with "Head is not open" when
  posting to /commit.
