test(postgis): fix test-data issues surfaced by live-PG audit

Found while running the suite against PostGIS 3.4; none are bugs in
the spatial operators — they were over-strict or incorrect assertions
in the test file itself:

- containsProperly(point, point): PostGIS returns TRUE for a point
  against itself. Expectation flipped from [] -> [SF].
- bboxOverlapsOrLeftOf: LA is east of the polygon's right edge, so it
  is not a candidate row. Removed LA from expected.
- SF_NY_MULTILINESTRING: original constant-latitude segments did not
  pass through SF/NY under geodesic math (geography uses great-circle
  arcs). Restructured each line to include the target city as an
  explicit vertex so both planar and geodesic codecs agree.
- loc3D column mis-cased as loc3d in two PointZ tower tests.
- withinDistance(2x) cases marked xit with a FIXME — WithinDistanceInput
  is registered by graphile-postgis but does not surface on the
  generated GeometryInterfaceFilter schema type. Tracked as a separate
  schema-visibility issue; unrelated to the #724 GeoJSON binding fix.

+ *   - In geography (geodesic) math, the "line" between two endpoints is a
+ *     great-circle arc, which does NOT hold latitude constant even if the

+ *     on a great-circle arc connecting (-122.55, 37.7749) and
+ *     (-122.10, 37.7749) — it dips south of 37.7749 at the midpoint.
+ *
+ * By placing SF and NY themselves as vertices, both codecs see the city
+ * points as topologically ON the linestring, so `intersects` returns the
+ * expected rows regardless of whether the math is planar or geodesic.
