Juan Biondi ac291f2473 docs: Add detailed webserver documentation (#446) 
## More detailed documentation

* **What is the goal of this PR?** 
Add more information about the exposed webserver.
* **What changes are included?**
Detailed documentation for the webserver endpoints
(`./docs/webserver-endpoints.md`)
Adding a table of content so it is easier to navigate directly to the
section you're interested on (Almost all `.md` files or at least all
those relevant)

## Additional Context

Not sure if this would get accepted but I thought it might be useful for
those trying to create separate apps that would sync files to the
device. It was at least to me trying to upload files using python as
stated
[here](https://github.com/crosspoint-reader/crosspoint-reader/discussions/434#discussioncomment-15545349)
