fix(nspd): rename migration 89→98, fix red lines ST_Area→ST_Length (#220)
- data/sql/98_*: rename from 89 to avoid collision with existing 89_drop_dead_brin
- _get_red_lines: ST_Length(ST_Intersection(planar)::geography) instead of
ST_Area(ST_Intersection(::geography, ::geography)) — fixes PostGIS 3.4
tolerance error and returns correct non-zero length for LINESTRING intersections
- Rename intersection_area_sqm → intersection_length_m across schema, TS types,
frontend component, and tests; add test_get_red_lines_db_exception_returns_empty
