refactor(repo): переход на pnpm monorepo с shadcn/ui и Fastify+Drizzle

Frontend:
- apps/web (Vite+TS, TanStack Router/Query, shadcn/ui @cfdm/ui base-nova)
- 10 страниц в routes/_auth/, Recharts через shadcn Chart, lucide-react
- формы на RHF + Zod (FormSheet/FormField)
- удалены Tabler, Chart.js, react-router-dom

Backend (параллельный трек):
- apps/api (Fastify 5 + Drizzle + better-sqlite3)
- packages/db: Drizzle-схема и repositories по сущностям
- packages/shared: Zod-контракты
- роуты с валидацией и единым форматом ошибок { error: { code, message } }
- sync/backup — заглушки 501 (billmanager-адаптеры переносятся отдельно)
- legacy Express оставлен как runtime по умолчанию (RUNTIME=express)

Infra:
- Dockerfile multi-stage под pnpm workspaces
- .dockerignore и docker-compose обновлены под monorepo

Rules:
- удалены нерелевантные правила (rust, cloudflare, server/frontend-conventions)
- project-structure.mdc и AGENTS.md переписаны под monorepo
- frontend-shadcn.mdc, shadcn-ui-production.mdc, sqlite.mdc обновлены
