refactor: separar PVPlantGeoreferencing, PVPlantImportGrid y PVPlantPlacement en submodulos

- PVPlantGeoreferencing → PVPlant/core/georef.py
- PVPlantImportGrid → PVPlant/import_grid/grid.py
- PVPlantPlacement → PVPlant/placement/placement.py

Los archivos originales ahora son wrappers de compatibilidad.
Preparado para revisión exhaustiva de PVPlantPlacement.
