Phase 0.7 — coordinate reprojection of an open SWMM model.

Iterates every node, link vertex chain, and subcatchment polygon and rewrites the stored coordinates via OGR. Sets the model's CRS string to the new authority. The caller is expected to mark the project dirty so the change persists on next save.
