worldgen: load structure templates and transform them like vanilla

LoadResolvedTemplate parses the extracted .nbt files with every palette entry resolved to concrete state IDs through an injected resolver, and TransformBlockPos reproduces StructureTemplate.transform's mirror-then- rotate order around the pivot, including all three quarter-turn cases read off the bytecode. MthGetSeed gives processors their per-block positional Legacy stream. Verified against the real ruined_portal templates: every block lands inside the declared size for all eight mirror/rotation combinations.
