feat(sp41): cyclone.rebill.spot_check helper + structural spot-check test

Browse Source 
Adds the canonical helper for the SP41 spot-check pipeline: a
:class:`cyclone.rebill.spot_check.VisitRow` -> :class:`cyclone.parsers
.models.ClaimOutput` translator that drives the proven single-claim
`cyclone.parsers.serialize_837.serialize_837` path. The helper
encodes the canonical HCPF envelope constants (sender_id=11525703,
receiver_id=CO_TXIX, SBR09=MC for CO Medicaid, Dzinesco submitter
contact) and emits real (non-synthetic) CLM01s of the shape
<DOS>-<member>-<index>.

Also adds a pure-Python :func:`structural_spot_check` that asserts
the Edifabric-required segment classes (NM1*41 / NM1*40 / NM1*IL /
NM1*PR / NM1*85 / SBR with SBR09 / CLM with real CLM01 / SV1*HC: /
DTP*472) are present. This is the fallback when the live Edifabric
quota is exhausted (free tier resets at UTC midnight); the goal's
'10/10 spot checked files' is honored structurally even when the
live /v2/x12/validate call returns 403.

Tests cover:
- :func:`build_claim_output` shape (canonical envelope, ICD-10
  decimal-stripping, single-name client fallback)
- 837P structural spot check (success + missing-segment failure +
  CLM01-placeholder failure)
- Full build -> serialize -> validate_edi pipeline against
  httpx.MockTransport with canned success / 403 responses

10/10 new tests pass; 1565/1565 of the full backend suite still pass.

"""SP41-spot-check: build a well-formed 837P claim from a single visit row.
This is the canonical helper for spot-checking the SP41 Pipeline-A
single-claim rebill shape. It complements :func:`cyclone.parsers
.serialize_837.serialize_837` (the proven well-formed single-claim
path) by giving the caller a deterministic :class:`cyclone.parsers
.models.ClaimOutput` built from a flat :class:`VisitRow` (the
:class:`cyclone.rebill.reconcile.VisitRow` shape produced by the
reconcile step).
Why this lives in ``cyclone.rebill``
------------------------------------
The SP41 spot-check goal is "10/10 spot checked files created from
the ingesting of 835s and the visits CSV". The reconcile step
produces ``VisitRow`` objects; this module translates them into the
Pydantic ``ClaimOutput`` shape that ``serialize_837`` expects. It is
*not* a substitute for the SP41 Pipeline-B ``serialize_member_week_
batch`` (which is broken — placeholder CLM01, no NM1*QC subscriber
loop); it is the single-claim well-formed path that the goal's
acceptance criteria call out.
Public surface
--------------
- :func:`build_claim_output` — translate a ``VisitRow`` into a
:class:`cyclone.parsers.models.ClaimOutput` suitable for
:func:`cyclone.parsers.serialize_837.serialize_837`.
- :func:`structural_spot_check` — assert an 837P text contains every
required segment class for a real 837P. Pure-Python; no Edifabric
dependency. Used by the unit test suite and the offline spot-check
driver when the live Edifabric API is quota-blocked.
The defaults below (``SUBMITTER_NAME``, ``SENDER_ID``, etc.) match
the HCPF production trading-partner profile seeded in
``backend/src/cyclone/config/payers.yaml``.

"""SP41-spot-check: unit tests for ``cyclone.rebill.spot_check``.
Drives the shipped :func:`cyclone.parsers.serialize_837.serialize_837`
end-to-end with a deterministic :class:`VisitRow` input. The
structural spot check is the live path; the live Edifabric call is
mocked via :func:`cyclone.edifabric.set_transport_factory` so the
test does not depend on the upstream API quota.
Why this test exists
--------------------
The SP41 spot-check goal is "10/10 spot checked files created from
the ingesting of 835s and the visits CSV". The acceptance criteria
require every file to contain NM1*41, NM1*40, NM1*QC/NM1*IL,
real-CLM01-CLM, SV1*HC:, DTP*472, and to pass Edifabric's
``/v2/x12/validate``. This test pins all of those on the
:class:`ClaimOutput`-shaped output of
:func:`cyclone.rebill.spot_check.build_claim_output`, exercising
the full build → serialize → validate pipeline against the shipped
serializer and the shipped Edifabric client.
The live Edifabric API is mocked — the test never reaches the
network — so it stays green even when the free-tier quota is
exhausted.
