Accept object for Fully Kiosk set_config service

[cgarwood]

Proposed change

Some Fully Kiosk Browser configuration options expect JSON. Updating the service schema to accept an object to allow templates to work in the service call.

Previously attempting to use templates for these values would result in:
Failed to perform the action fully_kiosk.set_config. expected str for dictionary value @ data['value']. Got None

Fixes #101071

So what kind of config can we set with this? How many options are there? Would it be logical to create a service per config?

This lets you set any of the ~300 configuration options under the Settings tab in the Fully Kiosk app. Toolbars/appearance, screensaver settings, zoom/scaling, power settings, there's a ton of different options.
