As a developer, I would like to show custom UI in Aspire Dashboard, especially for custom resource commands, so that I can confirm with the user that they want to take the action, or prompt them for input.

As it stands, we can add custom commands to resources, but there is no way to show any UI or prompt (that I'm aware of). I have implemented a "Apply EFCore Migrations" custom command similar to those shown in @DamianEdwards demo here. It works as advertised, but I would like to be able to integrate further in the AppHost UI. In this case I also have a "Delete and recreate database" command and I would like to prompt the developer "Are you sure?".

Describe the solution you'd like

In addition to prompting the user to be sure they want to execute a command, I could see other UI hooks into App Host being useful. Some additional use cases:

• Prompt the user for input. For example, a 'Recreate Database with Data Seed' may prompt the user to pick the amount of seed data they want.
• Show a tab in the left sidebar. For example, developers might create a help page or dashboard specific to their application. A 3rd party vendor might provide a dashboard that rolls up traces/metrics/logs in unique ways or provides a UI for managing a database instance during development.
• Add a link in the top right sidebar. For example, developers might link to their project wiki, source code repository, etc.
