App proxy components

Sets up a Remix <Form> component that works when rendered on an app proxy page. Supports any properties accepted by the <Form> component. Because Remix doesn't support URL rewriting, any route using this component should match the pathname of the proxy URL exactly, and end in a trailing slash (e.g., >/apps/proxy/), or set the Remix Form prop navigate to false.

Sets up an HTML element that works when rendered behind an app proxy. Supports any properties accepted by the HTML element.
