feat: first draft end to end Create API

[MaikelVeen]

This PR implements the first end to end implementation for the Create endpoint.
As followup the following needs to be done for this endpoint to be complete:

• [] Return the created item
• [] Catch unique violation constraints and ensure those are returned as BadRequest
• [] Implement the ErrorHandler
• [] Set the UUID if client did not set it

🚀 Features

• Add a NoopLogger to help in tests
• Implement unmarshal in ItemsCreate
• Connect handler with repository
• Add migrate command

🚜 Refactor

• Add metadata to Item, remove path and add back DisplayName
