Gorky Park (6), Red Square area (10), and Moscow-City (6) landmarks
with real historical/architectural facts, each with short/medium/long
narration text in Russian and English. Widened built_year to
varchar(128) since several entries need more than a bare year (e.g.
demolition/reconstruction ranges).
Verified end-to-end against the live backend: all 22 places load via
seed_loader, nearby search returns correctly distance-sorted results
with radius expansion in sparser areas (confirmed at Gorky Park,
900m), and place detail/search-fallback endpoints return full
bilingual content. Full pytest suite passes.
