Erik 4763b973da fix(terrain): use real LandHeightTable from Region dat
Phase 1 simplified per-vertex height as byte * 2.0f, but AC stores
heights as byte indices into a 256-entry non-linear float lookup
(Region.LandDefs.LandHeightTable). Static object placements in
LandBlockInfo use the real table, so terrain rendered with the
simplified scale left buildings floating or buried.

LandblockMesh.Build now takes an explicit float[] heightTable so
the core code stays testable without a DatCollection. GameWindow
loads Region id 0x13000000 once at startup and passes its
LandDefs.LandHeightTable into every landblock mesh build. The
Phase 1 tests use an identity table (i * 2f for i in 0..255) so
their expectations remain unchanged.

Addresses the 'buildings buried and floating' issue the user
observed after the Phase 2a visual checkpoint.
