## Any other notes
- Updates Settings on Big Sur to use a toolbar to swap between root-level settings screens.
- Fixes blurry web view, only on Big Sur.
- `UISwitch` as a checkbox looks kind of weird; may need to do some Eureka-level changes to make SwitchRow use the `title` property on `UISwitch` to make it connected so the whole thing is clickable. This gets weird because the font size is larger for this property.

Static video/audio attachments in dynamic category (home-assistant#1597)

## Any other notes
Dynamic actions require the 'DYNAMIC' category but our content extension causes attachments to not appear and we want every possible feature to work with just this category.
