fix(ci,ai-chat): восстановить зелёный CI на develop

Чинит два падения прогона Develop (#29104398390):

A. Интеграционные тесты сервера (10 failed) падали с
   `TypeError: this.environment.isAiChatFinalStepLockdownEnabled is not a function`.
   Мерж #444 добавил вызов этого метода в AiChatService.stream, но два
   интеграционных фикстура не обновили env-стаб. Добавлен
   `isAiChatFinalStepLockdownEnabled: () => false` в 4 стаба
   (ai-chat-attach.int-spec.ts, ai-chat-stream.int-spec.ts).

B. Job e2e-server не компилировал app.e2e-spec.ts:
   `TS2307: Cannot find module '@docmost/mcp'`. Рефактор #446 добавил
   тип-импорт из @docmost/mcp в docmost-client.loader.ts, но job не
   собирал этот пакет (его build/ в gitignore). Добавлен шаг
   `Build mcp` в e2e-server (по образцу e2e-mcp / mcp-server-parity).

Только тесты и CI-конфиг; продакшн-логика не менялась.
