For FLEXIBLE (Remotion / FlexStory) templates the render uses fixed positions —
dragging or resizing a layer on the Konva canvas does nothing to the output, which
is confusing. Make the canvas a read-only PREVIEW for those projects: the Konva
Layer is listening=false (no drag/select/transform), the Transformer is hidden, and
the auto-thumbnail capture is skipped so the flat Konva snapshot can't overwrite the
real rendered per-scene image. Editing happens only through the field form
(BlockFieldForm). AE/Konva templates are unchanged. Gated on isFlexStoryProject().
