Add missing dialog tests (#11133)

Leveraging the fancy coverage functionality of #10930, this PR aims to
add coverage to missing dialogue models.

This has proven quite constructive as many of the dialogues have since
been shown to be bugged.
- The APINodes sign in dialog that displays when attempting to run a
workflow containing Partner nodes while not logged in was intended to
display a list of nodes required to execute the workflow. The import for
this component was forgotten in the original commit (#3532) and the
backing component was later knipped
- Error dialogs resulting are intended to display the file responsible
for the error, but the prop was accidentally left out during the
refactoring of #3265
- ~~The node library migration (#8548) failed to include the 'Edit
Blueprint' button, and had incorrect sizing and color on the 'Delete
Blueprint' button.~~
- On request, the library button changes were spun out to a separate PR
