feat: Complete Shiplogic integration with mobile-optimized ops workflow

**Shiplogic API Integration:**
- Fixed API base URL configuration (removed /api suffix)
- Implemented comprehensive request/response logging for rates and shipments endpoints
- Fixed PDF fetching: API returns S3 URLs, now downloads actual PDFs from S3
- Added tests and mock API responses for local development (routes/shiplogic-mock.php)

**Courier Service Enhancements:**
- Added redownloadShipmentPdfs() public method for re-downloading corrupted PDFs
- Enhanced error logging with full request/response bodies for debugging
- Proper binary PDF storage using Laravel Storage facade
- URL and S3 download handling for Shiplogic API responses

**Workflow & Operations:**
- Changed to manual "Ready for Collection" button instead of automatic move
- Operators now: scan QR → apply labels → click "Ready for Collection" → moves to Awaiting Collection
- Removed duplicate PDF attachments to Trello (was adding twice from two listeners)
- Fixed NotifySlackOnShipmentCreated to only handle Slack notifications

**Mobile-Optimized Ops Page:**
- Removed QR code display from order detail page
- Implemented responsive single-column layout for mobile phones
- Large touch-friendly buttons (full width, increased padding)
- Bold typography for better readability on small screens
- Larger input fields and tracking number displays
- Clear step-by-step instructions for warehouse operators
- Re-download PDF button for damaged/corrupted labels

**New Features:**
- POST /ops/orders/{uuid}/ready-for-collection endpoint
- Re-download PDFs functionality accessible from awaiting_collection and in_transit states
- Full audit logging for all operations via ops interface
- Proper error handling and user feedback

**Testing:**
- Added ShipmentCreationTest with mock HTTP client
- Created comprehensive testing guide (SHIPLOGIC_TESTING.md)
- Mock API routes for local development without hitting live API
