**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.
**What**
- Bumps `class-variance-authority` to new beta version - `cva@beta`.
- Updates all usages of `cva` to new API.
- Clear up the naming of types in `usePrompt`
**Why**
- A bug in how `class-variance-authority` exported its types mean that we were relying on patching the package to ensure that the correct types made it into the build of our UI package. This was important to ensure intellisense for component variants, such as `<Button size="large" />`. Previously in the UI monorepo, having the patch was enough to ensure that the correct types made it into the build, but that was not the case after we moved the design system to the core repo. The issue with types is fixed in the `@1` version of `cva` which is currently in beta. I have pinpointed the version to the current beta version to ensure stability despite the package currently being in beta.
