"""
Admin API endpoints for Module Configuration Management.

Provides per-module configuration for platforms:
- GET /module-config/platforms/{platform_id}/modules/{module_code}/config - Get module config
- PUT /module-config/platforms/{platform_id}/modules/{module_code}/config - Update module config
- GET /module-config/defaults/{module_code} - Get config defaults for a module

All endpoints require super admin access.
