feat(dashboard,types,js-sdk,ui): Add missing Price List features (#7856)

**What**
- Adds missing features to Price List domain
- Adds `StackedFocusModal` and `StackedDrawer` components that should replace SplitView across the project.
- Add Footer to FocusModal
- Adds missing js-sdk functions and types

**Note**
The DatePickers in the PriceLists forms do not work as intended atm. The component is broken, and needs to be fixed. I am working on a fix, but choose to move that work into a separate branch, to prevent this PR from getting bigger then it already is. Will update once the fixes have been merged.
