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.
