* [bugfix] Correctly style inputs and buttons
<input>, <textarea>, and <button> were incorrectly using the system-ui font previously; this commit fixes that. text-align: center; was added to <button> due to an inconsistency with .button where text-align would be off.
* [chore] Update binary installation instructions
This commit updates the example release mentioned in the docs, and mentions Caddy in the reverse proxy options.
* [bugfix] Remove redundant Caddyfile
Caddy automatically upgrades HTTP to HTTPS (see https://caddyserver.com/docs/automatic-https) so the upgrading part of the Caddyfile is redundant.
* Add instructions for working with Caddy 2
Add instructions for working with Caddy 2. Some texts are duplicated from the NGINX part (mainly the configuration part, about systemctl).
* Add new Caddy docs to mkdocs.yml
Adds the new Caddy document to the document tree
* Remove up and downstream headers from configuration
Removed the header statements for the proxy, as proxying those are transparant. Kept the flush_interval directive, disabling the response buffer completely so we can write without delays.
* Update caddy.md
Corrects the opening link
* Apply comments mentioned in PR
@igalic mentioned a few comments to improve these docs. I've processed those in this PR.
