[Feature] Combined Docker image

3

- combined Docker image with [Caddy](https://caddyserver.com/docs/), [supervisord](http://supervisord.org/introduction.html), [PHP-fpm](https://www.php.net/manual/en/install.fpm.php) - new workflow to build both flavours of the image (davis, davis-standalone)

**Issue**: php-imap was removed as deprecated from PHP8.4 See https://github.com/tchapi/davis/issues/195 Using https://www.php-imap.com/ as a replacement
