fix(codegen): add GeoJSONFilter for PostGIS geometry/geography fields

Adds GeoJSON/Geometry/GeometryPoint/Point → GeoJSONFilter mapping to
SCALAR_FILTER_MAP so PostGIS geometry columns appear in generated filter
types instead of being silently omitted.

Changes:
- Add GeoJSON, Geometry, GeometryPoint, Point to SCALAR_FILTER_MAP
- Add GeoJSONFilter config with equality/distinct operators
- Add GeoJSONFilter unit test
- Add PostGIS schema fixture (example-postgis.schema.graphql)
- Add 13 PostGIS integration tests (Place/Route with GeoJSON columns)
- Update 14 snapshots to include GeoJSONFilter
