Update and expand documentation screenshots and gallery

Added new screenshots for health, settings, and authentication pages, updated several existing images, and removed obsolete ones. The gallery documentation was updated to reflect the new and reorganized screenshots, providing a more comprehensive and up-to-date visual overview of the application's UI. Minor formatting cleanups were also made in the developer and getting started guides.

 # Getting started
 
----
-
 Welcome to the guide for getting started on hosting your own production instance of Endurain. Like many other services, Endurain is easiest to get up and running trough Docker compose. It is possible to get Endurain up and running without a domain and reverse proxy, but this guide assumes you want to use a reverse proxy and your domain. Endurain can run on any computer that support OCI containers, but in this guide we are using Debian 13 (should also work with 12).
 
 ## Prerequisites
