feat: add last refreshed timestamp to modules and CDN sources

Introduced a new field, last_refreshed_at, to track the last successful update time for modules and CDN sources. Updated the database schema, API responses, and internal logic to support this feature. Enhanced the frontend to display the last refreshed timestamp, improving visibility into the data update status for users.
