Update `packages/ui` to use the latest shadcn/ui BaseUI components

See: https://x.com/shadcn/status/2013641788745978276?s=20

The current implementation has some changes made by me due to errors in how the previous shadcn/ui components were set up. Let's compare our implementation to the new version and update where they differ (not considering changes due to formatting or linti rules).
