Update an existing note. This is a full update: fields omitted from the body are cleared. The note stays attached to its record; for a person note, set family to move it between the person and their household's family. First retrieve the current note from /api/notes/{id}, apply your changes, then send back the full object. The required permission depends on the note's link type: people and family notes require Write Notes; connection notes require Full Write Connections; batches notes require Limited Write Contributions; business notes require Limited Write Contributions or Full Write Accounting; and groups notes require group admin access with note permissions (Limited Write Groups).
