This PR cleans up the application creation API with stricter validations
on the input. We're also moving the `workspaceId` from the query
parameter into the body, so it can be validated togather and all input
data is in one place. Simplifies code both in client and server.
No additional changes for EE, and no conflicts either, and al unit and
Cypress tests pass.
