MCP Apps support

[Shubhdeep12]

It can be great if resend-mcp supports MCP Apps.

here are some use cases that i can think of currently

• AI Agent has some(or not having) some details about email and user asks for sending emails, using MCP Apps - AI Agent can return a prefilled(or empty) form to the user in the chat.
• Metrics - to display charts
• User can visualize templates and choose from them.
  and many more..

POC by @Shubhdeep12 : #55 I think we could look more into this as soon as we have a hosted MCP server.
