Ильяс Султанов 254950f151 DI2 внедрение, таск 1: серверная интеграция Data-Insight2 (server/finance-di2)
- Копия DI2-сервера в server/finance-di2/ с правками: schema/db-client/cache/table-config/override-tables/google-auth/audit-agent/routes
- db-client — обёртка над существующим пулом server/finance/db-client (второй пул не создаётся, добавлен экспорт isConnectionError)
- ai-config.ts — чистое IO конфигов из ai-agent.ts без Telegram-поллинга; роуты /api/ai/toggle и /api/ai/status удалены, без compression/startAuditScheduler/autoStartIfEnabled
- Обёртка registerDi2Routes с auth-gate (authenticateToken + finance.manage), регистрация строго перед registerFinanceRoutes
- Статика /di2 из dist/public-di2 перед веткой vite/static (dev и prod)
- Фикс предсуществующего бага DI2: buildGlobalExclusionConditions без cats в /api/profitability
