feat(place): add wiki location index lookup

Add wiki summary, URLs, and population data from wiki_index.db to
place detail and reverse geocode responses.

- Add lib/wiki_index.py: SQLite read-only lookup module
- Enrich /api/place responses via _enrich_with_wiki_index()
- Enrich /api/reverse responses via _enrich_reverse_result_with_wiki()
- Gate on has_kiwix_wiki feature flag (default false in home.yaml)
- Direct match only on place_name + osm_key + osm_value + state + country_code
- Additive fields: wiki_summary, wiki_url, wikivoyage_url, wiki_population

DB path: /opt/recon/data/wiki_index.db
