Form Save UX

Scenarios:

• A new form (creating author), that is totally empty
  • Currently we do not show validation errors until fields are touched, so likely invalid but no errors showing
  • If we show "Submit" enabled, clicking Submit "touches" all the fields, and you see the errors
• An edit form (editing author) with no changes
• A duplicate from (creating new author from existing)
  • dirty=false (technically user hasn't changed anything)
  • valid=true
