From: Franoosh <uinarf@autistici.org>
Date: Wed, 15 Oct 2025 14:42:29 +0200
Subject: Added camera support. Movement recognition and video streaming. Web
 server and frontend. Work in progress. To be fixed: frontend reloading
 information about client and a page after major changes like camera name or
 address change, camera removal. Add certificates before testing on actual
 distributed hardware. Add user login logic.
