Feat: switch component

[rosejbon]

Part of the move away from Emotion to set up our design system. This is the work to add a switch component to the design system styling it with just css and to replace existing short text inputs with this new component. See the Badge component as an example.

This component already exists, we just need to move it into the design system and remove the emotion styling of it. https://github.com/public-convenience-ltd/toiletmap/tree/main/src/components/Switch
