- Fix printer QR code not rendering on initial load (same race condition)
- Add model image to equipment badge via imageurl from Model table
- Fix white-on-white machine number text on badge, tighten barcode spacing
- Add PaginationBar component used across all list pages
- Split monolithic router into per-plugin route modules
- Fix 25 GET API endpoints returning 401 (jwt_required -> optional=True)
- Align list page columns across Equipment, PCs, and Network pages
- Add print views: EquipmentBadge, PrinterQRSingle, PrinterQRBatch, USBLabelBatch
- Add PC Relationships report, migration docs, and CLAUDE.md project guide
