feat: add mandatory vendor onboarding wizard

Implement 4-step onboarding flow for new vendors after signup:
- Step 1: Company profile setup
- Step 2: Letzshop API configuration with connection testing
- Step 3: Product & order import CSV URL configuration
- Step 4: Historical order sync with progress bar

Key features:
- Blocks dashboard access until completed
- Step indicators with visual progress
- Resume capability (progress persisted in DB)
- Admin skip capability for support cases

# Vendor Onboarding System
The vendor onboarding system is a mandatory 4-step wizard that guides new vendors through the initial setup process after signup. Dashboard access is blocked until onboarding is completed.
## Overview
The onboarding wizard consists of four sequential steps:
1. **Company Profile Setup** - Basic company and contact information
2. **Letzshop API Configuration** - Connect to Letzshop marketplace
3. **Product & Order Import Configuration** - Set up CSV feed URLs
4. **Order Sync** - Import historical orders with progress tracking
## User Flow
```
Signup Complete
Redirect to /vendor/{code}/onboarding
Step 1: Company Profile
Step 2: Letzshop API (with connection test)
Step 3: Product Import Config
Step 4: Order Sync (with progress bar)
Onboarding Complete
Redirect to Dashboard
```
## Key Features
### Mandatory Completion
- Dashboard and other protected routes redirect to onboarding if not completed
- Admin can skip onboarding for support cases (via admin API)
### Step Validation
- Steps must be completed in order (no skipping ahead)
- Each step validates required fields before proceeding
### Progress Persistence
- Onboarding progress is saved in the database
- Users can resume from where they left off
- Page reload doesn't lose progress
### Connection Testing
- Step 2 includes real-time Letzshop API connection testing
- Shows success/failure status before saving credentials
### Historical Import
- Step 4 triggers a background job for order import
- Real-time progress bar with polling (2-second intervals)
- Shows order count as import progresses
## Database Model
### VendorOnboarding Table
| Column | Type | Description |
|--------|------|-------------|
| id | Integer | Primary key |
| vendor_id | Integer | Foreign key to vendors (unique) |
| status | String(20) | not_started, in_progress, completed, skipped |
| current_step | String(30) | Current step identifier |
| step_*_completed | Boolean | Completion flag per step |
| step_*_completed_at | DateTime | Completion timestamp per step |
| skipped_by_admin | Boolean | Admin override flag |
| skipped_reason | Text | Reason for skip (admin) |
### Onboarding Steps Enum
```python
class OnboardingStep(str, enum.Enum):
COMPANY_PROFILE = "company_profile"
LETZSHOP_API = "letzshop_api"
PRODUCT_IMPORT = "product_import"
ORDER_SYNC = "order_sync"
```
## API Endpoints
All endpoints are under `/api/v1/vendor/onboarding/`:
| Method | Endpoint | Description |
|--------|----------|-------------|
| GET | `/status` | Get full onboarding status |
| GET | `/step/company-profile` | Get company profile data |
| POST | `/step/company-profile` | Save company profile |
| POST | `/step/letzshop-api/test` | Test API connection |
| POST | `/step/letzshop-api` | Save API credentials |
| GET | `/step/product-import` | Get import config |
| POST | `/step/product-import` | Save import config |
| POST | `/step/order-sync/trigger` | Start historical import |
| GET | `/step/order-sync/progress/{job_id}` | Get import progress |
| POST | `/step/order-sync/complete` | Complete onboarding |
## Integration Points
### Signup Flow
When a vendor is created during signup, an onboarding record is automatically created:
```python
# In platform_signup_service.py
onboarding_service = OnboardingService(db)
onboarding_service.create_onboarding(vendor.id)
```
### Route Protection
Protected routes check onboarding status and redirect if not completed:
```python
# In vendor_pages.py
onboarding_service = OnboardingService(db)
if not onboarding_service.is_completed(current_user.token_vendor_id):
return RedirectResponse(f"/vendor/{vendor_code}/onboarding")
```
### Historical Import
Step 4 uses the existing `LetzshopHistoricalImportJob` infrastructure:
```python
order_service = LetzshopOrderService(db)
job = order_service.create_historical_import_job(vendor_id, user_id)
```
## Frontend Implementation
### Template
`app/templates/vendor/onboarding.html`:
- Standalone page (doesn't use vendor base template)
- Progress indicator with step circles
- Animated transitions between steps
- Real-time sync progress bar
### JavaScript
`static/vendor/js/onboarding.js`:
- Alpine.js component
- API calls for each step
- Connection test functionality
- Progress polling for order sync
## Admin Skip Capability
For support cases, admins can skip onboarding:
```python
onboarding_service.skip_onboarding(
vendor_id=vendor_id,
admin_user_id=admin_user_id,
reason="Manual setup required for migration"
)
```
This sets `skipped_by_admin=True` and allows dashboard access without completing all steps.

## Testing
Run the onboarding tests:
```bash
pytest tests/integration/api/v1/vendor/test_onboarding.py -v
```
## Configuration
No additional configuration is required. The onboarding system uses existing configurations:
- Letzshop API: Uses `LetzshopCredentialsService`
- Order Import: Uses `LetzshopOrderService`
- Email: Uses `EmailService` for welcome email (sent after signup)
