Palette blueprints, searched nodes and moving blocks shared one engine
but only the single current target line was visible, so there was no way
to see where a dragged item could land. While a drag is active the
overlay now outlines every valid dropzone with the engine's own
predicates (accepts / acceptsInSlot, blueprint refusal, self-exclusion):
containers in green, fitting slots in blue with a name tag, refused slots
dimmed red with a name tag so they read as "exists but not for this".
Tests: palette fit + slot-fallback, blueprint container/refused-slot,
node fit/refuse on the same slot, move self-exclusion; typecheck clean.
