feat: Add Telegram bot integration and task detail/delete UI

- Wire up Telegram bot with token, allowed users and username from .env
- Fix TaskBeat to handle direct tasks (Telegram/email) without sub_tasks
- Fix send_telegram_message to use run_coroutine_threadsafe (avoid event loop clash)
- Add TaskBeat watchdog thread for auto-restart on crash
- Reset stuck in_progress tasks on startup
- Add task detail page (/tasks/<id>) with full response/log view and auto-refresh
- Add task delete route (/tasks/delete/<id>) with confirmation
- Include agent sender info in Telegram task prompts
- Orchestrator self-updated knowledge base with Telegram contact info
