* fix: make AI-created free notes draggable by seeding default position and size
Free notes need explicit geometry to be draggable/resizable in the editor; UI-created notes always set position+size but agent-created notes omitted both, so they couldn't be moved until resized. Seed defaults in validateFlowNotes.
