"""Add the telegram_credentials table — the Telegram notifications bridge.
Singleton row (mirrors ``x_credentials``, migration 059) holding the
Fernet-encrypted bot token (from @BotFather) + chat id (the CEO's
destination). Additive and inert until real Telegram credentials are set and
``telegram_enabled`` is armed.
Revision ID: 074_telegram_credentials
Revises: 073_project_environments
Create Date: 2026-07-14
