Make mystery importer seed notes and tolerate sparse manifests

Add a notes[] array to the manifest (note exhibits with presentation),
so the Scene 6 phone-note board is reproducible from source instead of
hand-authored. Also default documents/folders/brief/subtitle so
narrative-only mysteries (e.g. barricelli-files) import cleanly.

Captures mysteries/barricelli-phone-note/mystery.json from the authored
template (note: "PHONE FOR GLITCH HUNTER / Call: 5550100").
