feat(search): build documents resolving term/authority labels; reindex_all

Implements build_document in the search crate: resolves Term and Authority
flexible-field values to their human-readable labels so reindex_all produces
documents that Meilisearch can match on label text, not raw UUIDs.
Adds integration test covering the full reindex→search round-trip.
