feat: Add A6 PDF QR stickers with human-readable order info

Implement QrStickerService to generate both SVG (web) and PDF (print) stickers:

- Generate 32x32mm QR codes using SimpleSoftwareIO
- Create A6 (148mm  105mm) PDF stickers using DomPDF
- Include human-readable info: order number, customer, status, date, tracking
- Store order type (STOCK/CUSTOM) with visual badge
- Add generation timestamp to footer

Create stickers/qr-sticker.blade.php template:
- Two-column layout: info left, QR right
- Styled for A6 landscape printing
- Shows order number, customer, status, date, tracking info
- QR code positioned for easy scanning
- Print-optimized CSS

Update GenerateQrCodeOnOrderCreated listener:
- Now calls QrStickerService::generateSticker()
- Generates both SVG and PDF on OrderCreated event
- Logs paths to both formats

Add OpsController::downloadSticker() endpoint:
- GET /ops/orders/{id}/sticker/download
- Returns PDF with filename QR-{order_number}.pdf
- Requires ops access authorization
- Logs all downloads with user context

Update ops order-detail view:
- Add download button for A6 sticker PDF
- Position next to QR code display
- Link to new sticker download route
