Adding file input to workflow forms + restrict/guide entry creation to be through specific flow

We're building ~almost~ everything of ops on Twenty. One of the things we've added in is expenses, as most of our expenses are linked to customer records (and it makes it super easy for our accountant to see what expenses linked to customers for tax purposes).

Therefore, I'd like the "create"-button (both in the top corner and in the table view) to trigger a workflow form where I can upload a PDF, and then process it with logic functions and AI skills.

This would also help for contract management etc.
