fix: resolve architecture validation errors in media and customers APIs

- Add proper media exceptions (MediaNotFoundException, MediaUploadException, etc.)
- Update media service to use exceptions from app/exceptions/media
- Remove direct HTTPException raises from vendor/media.py and vendor/customers.py
- Move db.query from customers API to service layer (get_customer_orders)
- Fix pagination macro call in vendor/media.html template
- Update media.js: add parent init call, PlatformSettings, apiClient.postFormData
- Add try/catch error handling to media.js init method
