feat: add full hierarchy context for breadcrumb navigation

- Pass facility/building/floor/room context through component tree
- HierarchyContext interface in SmartRack
- Breadcrumb now includes full path: Facility → Building → Floor → Room → Section → Tier

+ * FIX SECTION POSITIONS - 777 Wolfpack 3D Viewer
+ * 
+ * Problem: All sections (A1-A6, B1-B6) have identical coordinates,
+ * causing all Flower Rooms to stack on top of each other in the 3D viewer.
+ * 
+ * Solution: Offset each room's sections horizontally so they don't overlap.
+ * - Flower Room A sections: X offset = 0
+ * - Flower Room B sections: X offset = 700 (one room width)
+ * - Flower Room C sections: X offset = 0, Y offset = 700 (below Room A)
+ * 
+ * Run: node prisma/seed-fix-sections.js
