feat: complete marketplace module self-containment

Migrate marketplace module to self-contained structure:

- routes/api/admin.py - Admin API endpoints
- routes/api/vendor.py - Vendor API endpoints
- routes/pages/ - Page routes (placeholder)
- models/letzshop.py - Letzshop model
- models/marketplace_import_job.py - Import job model
- models/marketplace_product.py - Product model
- models/marketplace_product_translation.py - Translation model
- schemas/marketplace_import_job.py - Import job schemas
- schemas/marketplace_product.py - Product schemas
- locales/ - Translations (en, de, fr, lu)

Removed legacy route files replaced by api/ structure.
Updated __init__.py files to use new structure.
