rmancinasandClaude Opus 5 4d5008b545 feat(statements): OCR intake for scanned utility bills

Staff key 300+ utility statements per company per month by hand. This adds
the ingest -> split -> OCR -> match -> review pipeline that proposes customer
and amount per page instead (RECEIPT_CAPTURE_SPEC §2), posting through the
existing BillingService.createBatch seam with source=OCR and a per-document
captureRef so machine and hand capture share one write path and audit trail.

Everything was designed against 10 real scanned statements (46 pages of CFE,
CESPT and Telnor bills) rather than from the sample-free spec. The scans have
no text layer at all — they are camera images — so OCR is mandatory, and they
arrive bundled one customer per page. Measured on those pages the parser
identifies the provider 46/46 and reads an account reference 43/46; against
the dev database that is 39/46 (85%) exact auto-match, 40/46 identified, with
the rest genuine review cases. That closes the OCR-provider question in favour
of self-hosted Tesseract: it clears the bar for a queue where a human confirms
every row, and OcrProvider keeps a managed API a one-line swap.

The samples corrected three things the spec had wrong or unknown:

- Clave catastral is NOT predial. DATMEX.clave (934 rows) is what CESPT and
  predial bills print; DATMEX.predial, which PROPERTY_TAX.accountNumber holds,
  has 663 distinct values across 1135 rows and appears on no statement. The
  clave now lives on Property.cadastralKey as the matcher's secondary key;
  predial is left untouched. This had been blocking predial matching.
- Gas was recoverable: 160 of 334 DATMEX.gas values are real account numbers
  (the rest are ESTACIONARIO/CILINDRO descriptors), now in GAS.meterNumber.
- Phone is one billed line per property (534/18/1 across phone1/2/3), so the
  new TELEPHONE ServiceKind backfills from phone1 only, not three rows.

Matching is scoped to one column per service kind and never reads the customer
name — a CESPT receipt prints ARNAIZ ROSAS ELSA AURORA for an account this
office holds under CATT, RANDY, because the printed name is the registrant,
not the current owner. Where a provider prints a payment barcode it beats the
printed label (one CFE label OCR'd a digit too many while its barcode was
correct) and the two cross-check, with disagreement forcing review.

Confirming a document whose service had no reference writes it back, so gas
and any other cold start is a one-time cost rather than a permanent queue.

Verified end to end against the live dev API and MinIO: real scans uploaded
over HTTP, matched, confirmed against a check, and the resulting rows checked
in MySQL (negative amounts, captureSource=OCR, concept derived from the batch
kind, captureRef linking back to each page). Re-confirming a posted batch is
refused. Test data was removed afterwards.

rmancinasandClaude Opus 4.8 2c6a6bf60b feat(billing): shared statements module across both business lines
Plan step 6 — the payoff of the unified customer record: a utility charge
and an insurance payment finally sit on the same page, under the same
person, with a running balance.

API (apps/api/src/billing/):
- GET /billing — cross-customer movement browser. Search over customer,
  referencia, cheque, concepto and periodo; filters for business line,
  currency, charge-vs-credit, concept, origin table and a from/to date
  range; 5 sorts. Returns totals for the whole filtered set, not just the
  page, so a filtered view can't be misread as the full ledger.
- GET /billing/balances — per-customer receivables worklist with
  owing/credit/settled buckets and 4 sorts. Raw SQL (parameterized via
  Prisma.sql): needs conditional sums per currency and per direction in
  one pass plus ordering and pagination on a computed balance, none of
  which groupBy expresses.
- GET /billing/stats, /billing/facets, /billing/customers/:id.

Web:
- /estado-cuenta — two views over the same ledger, because staff ask two
  different questions: "Saldos por cliente" (who owes what) and
  "Movimientos" (every charge and credit).
- /estado-cuenta/[id] — the statement: balance per currency, the same
  balance split by business line, charges broken out by concept, and the
  full movement list with a running balance.
- Cross-linked from the customer and property detail pages.

Two data findings shape the whole module:

1. transactions.amount is a signed ledger. Every charge type is negative
   without exception (WATER 3115/3117, ELECTRIC 2191/2191, PROPERTY TAXES
   926/926, TRUST FEE 188/188) and every deposit type positive (CHECK and
   CASH DEPOSIT, PAYPAL, all of EFECTIVO). So SUM(amount) is the balance
   and negative means the customer owes the office.

2. Currency is not summable. 912 of the 1269 customers with a ledger move
   in both MXN and USD, the charge side is MXN-only while receipts arrive
   in both, and no per-movement exchange rate was ever stored. A single
   "total balance" would be a figure that never existed in the books, so
   every total is reported per currency and the balance filter/sort takes
   a currency argument rather than collapsing.

Also: type_transactions.nameEs is entirely null (the legacy TYPE OF TRX
ESPAÑOL column is empty in all 79 rows), so Spanish concept names come
from a label map in labels.ts; the entries that are payee names rather
than categories fall through untranslated, which is correct.
