Yet further app fixes (#9523)

- Prevent selection of note nodes
- Prevents selection  of nodes with errors
- A bit broader than the reported "can select missing nodes". A node
with an error is a node that can not execute and thus can not be used in
an app.
- Updates the typeform survey
- Add a collapsible list of all api nodes(/prices) contained in an app.
  - Needs to be prettied up for mobile still.
