feat(urethon): Manual Request Creation Frontend

[Dao-Ho]

Create a very simple UI for request creation.
Place this in the /requests/list route

In this UI ensure you have:

• a create button that opens up a modal to create a single request (hard code any values as needed)
• below the button is a list of requests in list view (no neeed for pagination, keep this UI very simple, the main component that you should focus on is the ux of the request creation)

Suggestions:

• Feel free to use shadcn ui for help with components
