add error handling if modules to change status are not found when discord breaks something in the future

[RoguedBear]

let the users know through a toast that AutoIdleOnAFK won't work if the status changing modules are not found.

this can also be shown by modifying the settings page. grey out those settings and add a visual block [broken]
toast can say plugin is broken please check the issues page or create a new one if it does not exist.

in this case, when the plugin becomes complex if one thing breaks, it won't render the entire plugin useless. you can still use it except parts of it can be broken. like check if you're in vc, in an activity etc
