feat(db): ObjectTag registry ratified + importer validation — resolves Q-049 (T-995)

The shipped 28-tag catalog palette is canonical (user ratification,
/whats-next refinement 2026-07-07). New machine-readable registry
wiki/economics/object_tag_vocabulary.toml (wall/roof/facade/street axes +
4 generic fallback terminals, Miri/Araminta co-owned header). Importer
validation in economy_import/traits.py: V-TT-03 (every catalog
allow/block/visual_bundle tag exists in the registry, axis-checked) and
V-TT-04 (fallback graph: non-generics declare a parent, chains acyclic,
resolve to a generic — absorbs T-1004's Phase-4 slice). Registry added to
generator_sources (stamp coverage); systems.db regenerated + stamped.
Q-049 marked Resolved — divergence is now a loud build failure.
