/**
 * Client for `apps/api` `/v1/quotes` (see apps/api/src/quotes/quotes.controller.ts,
 * quotes.service.ts, dto/*, and packages/database/src/repositories/quotes.ts
 * for the source of truth).
 *
 * Unlike Leads/Opportunities, Quotes pass the DB row straight through with
 * no repository-level mapper — the top-level response is snake_case. The
 * one exception is `items`, a JSONB column whose element shape
 * (`QuoteItem`) IS camelCase — a real inconsistency in the API, not a typo
 * here. Money fields (`implementation_fee`, `impl_geral`, `monthly_total`,
 * `contract_total`, `proposed_monthly_total`) come back as NUMERIC-typed
 * strings from Postgres — always `Number(...)` before formatting/math.
