Qonto Supplier Invoices API

# Provenance: MODELED-FROM-DOCS (2026-07-17).
# Qonto publishes a first-party OpenAPI 3.x document at
# https://api-doc.qonto.com/docs/business-api/reference/openapi_v2.yml and per-endpoint
# OpenAPI fragments under https://docs.qonto.com/api-reference/ . Those hosts are served
# behind Cloudflare and returned HTTP 403 to automated fetches during authoring, so this
# document was MODELED from the public documentation index (https://docs.qonto.com/llms.txt),
# the per-endpoint markdown fragments, and the getting-started auth/rate-limit pages.
# Base URLs, security schemes, and the /v2/transactions and /v2/sepa/transfers paths were
# confirmed verbatim from the docs; the remaining paths are modeled from documented
# resource operations and should be reconciled against the first-party spec when reachable.
