feat(tg-bot): unpin auto-forwarded channel posts

Telegram non-disableably auto-pins each channel post it auto-forwards into the linked discussion group. The bot now detects that message by Message.is_automatic_forward in the moderated chat (TELEGRAM_CHAT_ID) and unpins it by id, so a pin set by a human admin — or by the bot for another message — is never touched (no unpinAllChatMessages). Needs the can_pin_messages right in the chat; the startup self-check now also warns when it is missing. Bot-only; no wire/schema/DB change.
