Add Auto-Documenting Swagger Middleware

[adamgarcia4]

I've added a very nice Middleware that I developed on a different project.

Please see the screenshot for an example on how to use it.

Functionally, it allows you to specify a zod schema for inputs to the express handler (params, query, body, header).

It will do two things:

1. Dynamically Generate a swagger file from the schema middleware.
2. If you set the validateInput or validateOutput flags to true, it will reject inputs or outputs against that schema. I see that you do zod middleware validation in your routes. You can remove it from the handler.

I'm hosting the lovat-server here, and you can see the swagger middleware auto-generated from the one test route that I've created. If approved, we can start moving all the existing routes over to this.

https://lovat-server.onrender.com/swagger/
https://lovat-server.onrender.com/swagger.json

You'll get full API type safety as well as auto-documenting Swagger files!
