# Grandfather api_and_webhooks for existing accounts (cloud only).
#
# Adds api_and_webhooks to each account's manually_managed_features internal
# attribute so per-account billing reconciles never strip the feature from
# accounts that existed before the flag was introduced. Idempotent.
#
# Usage Examples:
#   # Grandfather a single account
#   ACCOUNT_ID=1 bundle exec rake api_and_webhooks:grandfather
#
#   # Grandfather all accounts in the installation
#   bundle exec rake api_and_webhooks:grandfather
# rubocop:disable Metrics/BlockLength
