Create the adminpage for albums and songs

[Equasa]

We have songs-categories on our website and app. This is something we need on the new website also.

We have a lot of posts on F-sektionen which need to be administrated. Therefor this issue is for the adminstration of posts.

Create a page for it which can be found in the sidebar of the Adminpage (see admin/AdminSidebar.tsx).

You need to use the AdminTable, look how this is implemented in for example admin/Events/page.tsx.

You should be able to sort the table and see the appropriate information.
