feat: initial dairy report generator
- chart1: линейный график цены + себестоимость + 3 сценария + маржа (bottom panel) - chart5: сгруппированные бары сценарий маржинальности - document.js: сборка DOCX (header/footer DT-style, KPI, callout, tables, images) - index.js: параметрический entry point generateReport(config) - examples/russia.js: полный пример для РФ - palette.js: DT-палитра синхронизирована с DESIGN_DAIRYTRENDS.md Tested: node examples/russia.js → 44KB DOCX, validation PASSED

* Chart 1 — Главный график отчёта:

* - Верхняя панель: линия закупочной цены (факт) + себестоимость + 3 сценария
|

* - Нижняя панель: барчарт маржинальности по периодам (история + прогноз)

* SVG → PNG via sharp.

* Параметры:

* costData: [{ date: 'YYYY-MM-DD', cost: number }] — себестоимость
