refactor: migrate modules from re-exports to canonical implementations

Move actual code implementations into module directories:
- orders: 5 services, 4 models, order/invoice schemas
- inventory: 3 services, 2 models, 30+ schemas
- customers: 3 services, 2 models, customer schemas
- messaging: 3 services, 2 models, message/notification schemas
- monitoring: background_tasks_service
- marketplace: 5+ services including letzshop submodule
- dev_tools: code_quality_service, test_runner_service
- billing: billing_service
- contracts: definition.py

Legacy files in app/services/, models/database/, models/schema/
now re-export from canonical module locations for backwards
compatibility. Architecture validator passes with 0 errors.

"""
Customer management service.
LEGACY LOCATION - Re-exports from module for backwards compatibility.
Handles customer registration, authentication, and profile management
with complete vendor isolation.
The canonical implementation is now in:
app/modules/customers/services/customer_service.py
This file exists to maintain backwards compatibility with code that
imports from the old location. All new code should import directly
from the module:
