feat: hotkeys (shortcuts) for all the settings (not just some of them)

[WofWca]

Like some people may find it useful to toggle the "Experimental algorithm" with a shortcut instead of having to open the popup and click it.

Also may think about displaying changes on the badge:

But need to keep in mind that I have not made some of the settings reactive (due to laziness), i.e. you need to toggle the extension or refresh the page for changes to take effect.
