feat(dashboard): Draft orders create (#6680)

**What**
- Adds Create draft order form
- Updates draft order details page to also display "custom" items.

**Note**
- Currently, the form is missing a way to input a discount code. Need to rethink this a bit, as the we can't implement the design in Figma.
- The current design is missing a way to select from a customers existing shipping addresses, we should add that to keep the features we have today.
- This PR uses `useInfiniteQuery` which does not work on our staging (due to duplicate dependencies as a result of building straight from the monorepo), so you will need to test locally.
