Introduce a globally-shared, non-tenant-scoped common_third_parties
table that mirrors the public subset of vendor metadata, plus a
one-shot cmd/common-third-parties-import CLI that seeds it from
packages/vendors/data.json. The catalog will back future flows (e.g.
vendor autocomplete) so each tenant no longer needs to duplicate the
same baseline data.
The importer is idempotent via ON CONFLICT (lower(name)) DO UPDATE
and prints inserted/updated counts. GIDs use gid.NilTenant since the
table is not tenant-scoped; uniqueness still comes from the entity
type plus 14 bytes of timestamp/random suffix.
