AIP-38 | List Connections

[bbovenzi]

Now that we have list connections in FastAPI. We should display them in the UI.

Steps:

• Turn the "Admin" button in the Nav into a menu, like we do with Docs or User with a Connections option
• Add a Connections page
• Within the Connections page, load the list of connections and render them in a table using our DataTable component. This should include limit/offset pagination and allow order_by columns that the API supports.
