Make slides more readable

Slides are cards with text that can be manually added into a symptom check and are displayed in between the normal question cards in the query run.

export interface SlideConfig {
	title?	: { translations: TranslationList }
	message	: { translations: TranslationList }
}

(Maybe rename this to something like InfoSlideConfig to avoid confusion?)

Current

Desired

The doctors told me that this is not readable for psychotic patients. The idea was to use one bullet-point per sentence or otherwise more spacing

See Andreas' comment below for implementation idea

title is currently never used btw

Testing

examples/ReposeSymptomCheckStore has symptom checks with slides.
