Move the manual tmp_u5c_test checks into the streamlined e2e suite as three
`kind: u5c` legs against the Demeter utxorpc endpoints. Converts the old
time-bounded run.sh approach to the standard exit-code gate via a WorkStats
finalization policy (3 blocks → exit 0); a #921-style regression (reset loop,
no apply events) never finalizes → timeout → fail.

API keys are parameterized as ${DMTR_UTXORPC_KEY_*} (resolved by envsubst from
GitHub secrets) rather than hardcoded — the scratch files held real-looking
keys and this repo is public. The e2e image is built --all-features, so U5C is
available (and now TLS-safe per the preceding crypto-provider fix).

The U5C source connects over TLS via tonic/rustls. In builds that pull more
than one rustls crypto provider (e.g. the `aws` feature brings in aws-lc-rs
alongside ring), rustls has no process-default provider and panics on the
first TLS handshake (`no process-level CryptoProvider available`). Install the
ring provider once at startup, gated on the `u5c` feature.

This only surfaced now because nothing exercised U5C in a multi-provider build;
the manual u5c tests built `--features u5c` alone (single provider).

v0.183.0 removes leios as a ledger era: the endorser-block types
(LeiosEndorserBlock, LeiosTransactionReference,
NewLeiosEndorserBlockFromCbor) moved from ledger/leios to ledger/common,
and the leios era id and its block/tx/header type constants were dropped.

- Repoint the three endorser-block usages in ouroboros/leios_merged.go and
  ledger/forging/forger.go to ledger/common (types unchanged).
- Update the nonce-stability-window era-dispatch test to use Dijkstra — the
  real post-Conway Praos era that production already enumerates — as the
  4k/f regression guard in place of the removed Leios era.
- Bump ouroboros-mock to v0.13.0, which renames its Dijkstra-era fixture
  decoders off the removed leios constants; v0.12.0 fails to compile against
  gouroboros v0.183.0.

No production behavior change; the endorser-block CBOR and the post-Conway
4k/f window are unchanged.

v0.183.0 removes leios as a ledger era and renames the Dijkstra era's
block/tx/header type constants accordingly. Update the fixture era decoders
to the new names: BlockTypeLeiosRanking -> BlockTypeDijkstra, TxTypeLeios ->
TxTypeDijkstra, BlockHeaderTypeLeios -> BlockHeaderTypeDijkstra (the
"dijkstra" era cases). No behavior change.

Move the run/dmtrcli logic out of e2e.yaml into .github/e2e/scripts/
(run-test.sh, setup-dmtr-socket.sh, stop-dmtr-tunnel.sh), invoked from the
workflow steps. Scripts read the same env vars the steps already set; committed
with the executable bit so they run after checkout.

The three relay.cnode-m1.demeter.run endpoints are different networks, not
redundant mainnet relays:
  :3000 = Mainnet, :3001 = PreProd, :3002 = Preview

Point the mainnet legs at :3000 (only) and the preview n2n legs at :3002,
replacing the public preview relay. (:3001/PreProd is unused — no preprod legs.)

Replace the IOG public mainnet relay with the three Demeter relay endpoints
(relay.cnode-m1.demeter.run:3000-3002) across the 5 mainnet n2n legs
(assert-n2n-mainnet-{origin,tip}, aws-{s3,sqs,lambda}).

Strenghten and polish rough edges of implementation:

* `runScript` now returns `Maybe AsyncBenchmarkControl` instead of
  fabricating a no-op control: submit modes that never start the
  benchmark machinery (LocalSocket, Ogmios) yield Nothing, and a
  failing run no longer dies with the misleading
  "AsyncBenchmarkControl uninitialized" error that masked the real
  one. noopBenchmarkControl is gone; both call sites in Command.hs
  only ever consumed fst, so they are unaffected.

* WebSocket failures (DNS, refused connection, handshake rejection,
  mid-stream drops, close frames) are caught around WS.runClient and
  converted into TxGenError instead of escaping as raw exceptions
  past the error machinery and logging shutdown.

* `parseOgmiosUrl` validates the scheme (plain `ws://` only; `wss://` was
  silently degrading to a plaintext connection), parses the port via
  readMaybe with a 1-65535 range check instead of a partial read
  (`ws://host:/` no longer crashes), and rejects empty hosts.

* Submission responses are subject to a 90s timeout (generous, since
  the node may hold submissions back under mempool pressure) and
  their JSON-RPC id is verified against the request id; a mismatched
  or null id is treated as a protocol fault and aborts the run with
  the offending response described.

* json_highlevel configs that set ogmiosUrl without debugMode: true
  are rejected at compile time with an explanatory error: Ogmios mode
  ignores tps/targetNodes and produces no benchmark metrics, so a
  config asking for a real benchmark must fail fast rather than run
  unpaced and unmeasured. Low-level json scripts are unaffected, and
  compileOptions fails before any node interaction.

* Polish: parseOgmiosUrl/parseOgmiosResponse/OgmiosResult exported to
  make them unit-testable, `fromMaybe Null` instead of `maybe Null id`,
  unused `RankNTypes` pragma dropped, haddock module header added,
  import list put in stylish-haskell order.
