Quick redirect for `/admin` for better ergo

Description

This PR adds a redirect from /admin to /admin/indexing/status in the web UI, which is the page linked to by the "Admin panel" button when clicking the profile badge in the top right corner.

I also took the liberty of changing the link for the "Admin panel" button to /admin.
