Closes the action loop — instead of polling the dashboard, the platform pushes actionable signals to Telegram. New hourly 'alerts' job dispatches four toggleable triggers, deduped via a new alert_log table (cooldown-based for qualified/S-R/digest, watermark-based for score deterioration). Admin → Settings gains a Telegram panel (write-only bot token, chat ID, per-trigger toggles, Send Test). Credentials follow DB > env precedence (TELEGRAM_BOT_TOKEN / _CHAT_ID). Backend: alert_service + AlertLog model + migration 005, scheduler job, admin endpoints/schema. Frontend: AlertSettings panel, hooks, api, types. Deploy: run alembic upgrade (new alert_log table).
