feat: enhance city status management in dashboard

- Change table to display cities based on popularity
- Modify button logic to toggle between "停用" (disable) and "激活" (activate) based on current city status

This update improves the usability of the Ahoy Dashboard by providing
clearer management options for city statuses. Users can now easily
activate or deactivate cities from the dashboard, enhancing overall
administrative efficiency.
