feat: Add Blade templates for ops QR interface (Phase 2)

Create state-driven UI templates:

Main Template (ops/order-detail.blade.php):
- Display order summary with status, type, customer, date
- Render QR code SVG for shop-floor access
- Conditionally include state-specific action forms
- Show order items, packing details, shipment info

Action Templates:
- ops/actions/packing.blade.php: Form to input weight/dimensions
- ops/actions/inspection.blade.php: Pass/Fail inspection with optional notes
- ops/actions/read-only.blade.php: Status display for read-only states

Error Pages:
- ops/order-not-found.blade.php: Invalid/expired QR token
- ops/unauthorized.blade.php: Insufficient permissions

All forms use AJAX submission with confirmation dialogs
