feat: set interaction_type at import and track cross-section normalizations

Newly imported items with a generic .nitro logicType stayed on interaction_type
'default' until the post-import verification sweep ran. Fall back to the same
auto-detected type used by the sweep (classname mechanic + keyword + real flags)
so imports carry the correct interaction immediately; updates keep their
existing emulator handler types.

Also count cross-section id alignments under a separate normalizedIds field in
reconcileFurniDataWithItemsBase so fixedIds keeps its original meaning.
