closes #73

Hey @iuioiua, this is incredibly rough right now, but you encouraged me to open something so we can iterate on the idea.

With these changes, then I can go to the following routes:

• http://localhost:8000/models
• http://localhost:8000/items
• http://localhost:8000/items/new

There are currently two major issues:

• The styling is horrible. I need to get the plugin to accept styles that get applied to the routes it creates.
• The plugin only works with pentagon right now. So most of the functionality doesn't work! I'm at least glad that I can show the items, otherwise I wouldn't even open this. Ideally the user of the plugin could map their own CRUD functions to types, instead of forcing the plugin user to create (possibly unnecessary/unwanted) pentagon models.

I will get to these enhancements at some point and then post an update here. Hopefully that will get rid of the pentagon and zod imports.

After those are dealt with, I can turn to a better layout (likely some sort of table) and then security / permissions.
