[ADD] web: Add new widget to toogle a boolean with a slider

Purpose
=======

Currently, it's not possible to activate a boolean on a non-editable list view without adding 2 buttons linked to a python method. These buttons aren't aligned and the result is not pretty.

This commit adds a new widget that allows to toggle a boolean record by record by clicking on the slider.
