feat(policy-ocr): read A.N.A. Seguros' two policy faces

A.N.A. is the Rosarito office's tourist auto book and the second carrier
the policy OCR pipeline reads. It ships two unrelated faces, and the split
is different from GMX's: GMX ships two documents about one policy, A.N.A.
ships two products.

  AUTOMOBILE (SPECIAL POLICY FOR TOURISTS)  insures a car; vehicle table,
                                            9 numbered sections, one
                                            LIMIT OF LIABILITY column
  DRIVER'S POLICY (the office: "licencia")  insures up to 5 named drivers;
                                            no vehicle at all, 6 unnumbered
                                            sections in a different order,
                                            SUM INSURED + PREMIUM columns

The four automobile products the office sells (amplia / responsabilidad
civil, annual / by-the-day) are the same layout with different numbers, so
they get one parser rather than four.

These are born-digital portal PDFs, so pdftotext -layout returns exact
columns and the driver's-policy parser uses that: its two value columns
print the same shape (100,000.00 usd. / 18.70 usd.) with no per-row label,
so horizontal position is the only thing separating them. The split comes
from the header's own offsets, not a constant, because they shift between
products; when it can't be read every amount is reported as a sum insured
and the reviewer is told, rather than half the premiums being filed as
coverage limits.

Three things the layout will punish a naive read for:

- Each PDF prints its face two or three times (ORIGINAL, AGENT COPY, then
  a receipt and three travel cards) and the pipeline concatenates every
  page before parsing. The coverage walk is bounded to the first copy and
  the driver list to the first POLICY HOLDER block. Unbounded, the licencia
  returns the same person three times, which reads as a three-driver policy
  rather than as a bug.
- The money row is read positionally off its header. An unused DISCOUNT
  prints as a bare "-", so "find the six amounts" shifts every value one
  column left on a discounted policy.
- Two five-digit numbers sit in the header band and only one is the agent
  clave; the agent's street address is "BENITO JUAREZ 25 No.50 INT 38",
  three lines above the No. cell holding the policy number.

Sections 6-8 print a PREMIUM where the others print a limit, so
ParsedCoverage gains an optional `premium` (GMX never fills it) and the
review table a column: $40 is what legal aid cost, not a $40 liability
limit. Exclusions follow the GMX rule and go in the risk label with a null
amount -- which matters more here, since a responsabilidad-civil policy
prints 0.00 for material damage and the two are identical on the page.

Also in this change:

- coveragePeriodDays is parsed and written. A.N.A. sells 3- and 4-day
  policies; Policy.coveragePeriodDays defaults to 365, so a weekend policy
  left at the default sits in the renewals window a year out. Derived from
  the dates, cross-checked against the printed DAYS cell, disagreement
  noted not resolved.
- Vehicles and named drivers are parsed, shown read-only in review, and
  written as Vehicle / InsuredDriver rows on confirm, skipping any already
  on the policy (VIN then plate; licence then name). The case that forces
  the skip is confirming a renewal onto an existing policy. Nothing is ever
  updated or deleted -- a changed plate lands as a second row for a human.
- Batch.provider is set from what the parsers actually claimed instead of
  being hardcoded "GMX", so a mixed upload is labelled as mixed and the
  header can never contradict its own documents. PolicyDocument.documentType
  follows the same rule (was hardcoded GMX_POLICY).
- matchNote becomes TEXT. It was VARCHAR(191) and the note trail was sliced
  to 190 chars, which cut the tail notes -- the "could not read X" ones.
- The policy detail page renders an array coveragesJson as a table. Both
  shapes have always been possible there, but the object renderer was the
  only one, so an OCR-confirmed policy showed a row per array index labelled
  "0", "1", "2" with [object Object] as the value. ANA makes that routine.

GMX is untouched behaviourally; its two parsers now spread a shared empty
base instead of listing every null field. 29 new parser cases against
verbatim pdftotext output of three real ANA PDFs, 53 in the suite.
