-- 097_fix_migrated_purchase_menu_label_icon.sql
--
-- Fixes the custom menu item created by migration 096: updates the label
-- from hardcoded English "Purchase" to "充值/订阅", and sets the icon_svg
-- to a credit-card SVG matching the sidebar CreditCardIcon.
--
-- Idempotent: only modifies items where id = 'migrated_purchase_subscription'.
