feat!(web): migrate UI from SvelteKit to React + shadcn/ui + ReUI

Web UI полностью переведён с SvelteKit на новый стек: React 19,
TanStack Router/Query/Table/Virtual, shadcn/ui (base-nova) и ReUI
enterprise-компоненты (data-grid, filters, autocomplete). Новый код
разложен по слоям: packages/ui (shadcn-примитивы), apps/web
(роуты, shared-обёртки, ReUI-адаптации).

BREAKING CHANGE: меняется структура и инструментинг фронтенда.

- apps/web/ — новый Vite + React-проект (@evobgp/web), file-based
  роуты TanStack Router; экраны dashboard, modules, monitoring,
  network, operations, schedule, settings, tenant-settings, access,
  directories.
- packages/ui/ — shadcn/ui-примитивы (@evobgp/ui) с общими стилями
  globals.css и cn-утилитой; CLI shadcn запускается из apps/web.
- apps/web/src/components/reui/ — enterprise-паттерны ReUI.
- pnpm workspace (pnpm-workspace.yaml, pnpm-lock.yaml, tsconfig.base.json)
  заменяет npm-проект в web/.
- web/ переименован в web-legacy-svelte/ (архив-референс для миграции);
  импорты оттуда запрещены правилом WEB-22.
- CI (.gitea/workflows/ci.yaml): job web переведён на Node 22 + pnpm 10
  (typecheck/lint/build через pnpm --filter @evobgp/web); пути триггеров
  обновлены под apps/web|packages/ui.
- deploy/docker/evobgp-web/Dockerfile: сборка из корня репозитория,
  pnpm install --frozen-lockfile, выход dist из apps/web/dist.
- .cursor/rules/web-shadcn.mdc, context7-stack.mdc, engineering.mdc,
  AGENTS.md — обновлены под React-стек (WEB-01..WEB-22, DOC-SYNC-06/07).

Проверки WEB-19 локально: typecheck, lint, build — exit 0.
