Merges worktree-h3-catchment-index. dim_locations now computes h3_cell_res5
(res 5, ~8.5km edge). location_profiles and dim_locations updated;
old location_opportunity_profile.sql already removed on master.
Conflict: location_opportunity_profile.sql deleted on master, kept deletion
and applied h3_cell_res4→res5 rename to location_profiles instead.

Combines city_market_profile and location_opportunity_profile into a
single serving model at (country_code, geoname_id) grain. Both Market
Score and Opportunity Score computed per location. City data enriched
via LEFT JOIN dim_cities on geoname_id.
Subtask 1/5: create new model (old models not yet removed).
