Use OSM as the single source of mountain passes

Replace the centcols CSV download/enrichment pipeline with OSM PBF
extraction as the primary (only) source: merge osmpass into mountain_pass,
drop the centcols table and model fields, filter to named passes with
elevation, and remove the centcols CLI flags.
