feat(polizas): OCR capture for insurance policy PDFs

Mirrors the utility statement intake on the insurance side: a policy_ocr
batch/document pair of tables, a GMX parser, a matcher keyed on
Policy.policyNumber, and a "Captura" screen under /polizas that proposes
policy -> customer for staff to confirm.

Lifts the OCR seam out of StatementsModule into its own OcrModule so
PolicyOcrModule can inject OCR_PROVIDER without taking on the rest of
the statement pipeline; StatementsModule now imports it and binds
nothing itself.
