Changes

• Updated the endpoint to integrate with the latest version of the Rucio server.
• Implemented the table component with AG Grid.
• Integrated the new streaming mechanism for efficient data handling.
• Added the subscription item to the site menu

Follow-up

• The current implementation lacks server-side rendering support for fetching account info. This can be addressed when revamping Rucio WebUI.
• The detailed view of subscriptions still relies on legacy pages, and its integration with the Rucio server remains broken.
