Persist Telegram chats in DB, auto-save from webhooks, click-to-copy

- Add TelegramChat model (bot_id, chat_id, title, type, username)
- Chats auto-saved when bot receives webhook messages
- New API: GET/DELETE chats, POST discover (merges from getUpdates)
- Cascade delete chats when bot is deleted
- Frontend: click chat row to copy chat ID to clipboard
- Frontend: delete button per chat, "Discover chats" sync button
- Add 4 i18n keys (EN/RU) for chat management
