Admin interfaces and controllers

[dginev]

As listed in the overarching 1.0 issue #43 , cortex is currently severely lacking from the user interface side. The only really finalized UI widget is the rerun button, but the administrative flow (register/extend corpus, register service, and etc for all CRUD on all components) is done exclusively via example rust scripts, such as tex_to_html_import, extend_corpora, register_service.

Those should really be admin interfaces in the web service, behind an authentication guard, in the very well-known and standard admin dashboard interface.

I have found the tool for the job on the OAuth 2 side, will ship a first admin dashboard in the coming week.
