Subject: Introduce EDIT and MANAGE methods

All admin "index" pages are moved under MANAGE, so that we can have (for
example) and normal "GET /posts" page later which would replace the
current index page, and potentially corresponding pages for the other
categories.

The EDIT method replaces the old `?edit` pattern, which normalizes how
we differentiate page functionality generally.
