feat: Add selectiveUnion for improved Superstruct error messaging (#…

…2696) Adds `selectiveUnion` and rewrites a bunch of structs to use this pattern. This helps alleviate a problem where Superstruct errors would be impossible to read. The idea of `selectiveUnion` is to be able to guide Superstruct validation more with simple checks that can be used to choose between validation paths. This combined with `typedUnion` makes it possible to have drastically improved error messages for structs that use unions. This PR rewrites some of the UI structs to use these new patterns, but is not necessarily exhaustive. It also adds support for refinements and coercion to `typedUnion`. Generally, this PR turns errors like this: ``` Invalid params: At path: ui -- Expected the value to satisfy a union of `union | union`, but received: "foo".' ``` into errors like this: ``` Invalid params: At path: ui -- Expected type to be one of: "Address", "Bold", "Box", "Button", "Copyable", "Divider", "Dropdown", "RadioGroup", "FileInput", "Form", "Heading", "Input", "Image", "Italic", "Link", "Row", "Spinner", "Text", "Tooltip", "Checkbox", "Card", "Icon", "Selector", "Section", "Container", but received: undefined. ``` This PR does not solve this problem for structs that use the `children()` utility function with more than one struct as the input (e.g. `Button`). These components will fail with something like: ``` Invalid params: At path: ui.props.children.1.props.children.props.children -- Expected the value to satisfy a union of `union | object | object`, but received: [object Object]. ``` There may also still be other UI components that fail with similar errors, however, this is a huge step forward in readability and therefore dev-ex.
