Build the spatial hierarchy panel from the loaded model's real IFC spatial structure instead of mock data: - helpers/element: add get_spatial_children (IsDecomposedBy -> RelatedObjects, filtered to spatial elements) to walk IfcProject -> IfcSite -> IfcBuilding -> IfcBuildingStorey -> IfcSpace. - SessionState: relay dataSourceReady as modelDataSourceReady (the .ifc for a sidecar hit loads asynchronously, so the tree can only build once it arrives). - spatial_hierarchy/View: walk the active model's IFC file into a TreeNode tree, naming nodes by Name (fallback to class), mapping site/building/storey kinds; siblings sorted with natural (numeric) collation. - spatial_hierarchy/Panel: tree now fills the panel height (setBodyExpanding + Expanding size policy); right-click menu for recursive Expand/Collapse Subtree and Expand/Collapse All. Add the concept of an active model: - SessionState: activeModelId / setActiveModelId / activeModelChanged; the first loaded model is active by default; reassigns/clears on removal. - Models panel: clicking a model makes it active; its cube icon is drawn with the accent colour (makeAccentSvgIcon) via FederationItemModel::setActiveModelId. - The spatial hierarchy reflects only the active model.
