feat: Add ConfigurationCQ - Phase 2 Application Layer

Implemented complete CQRS pattern for System Configuration management:

Commands:
- SetConfigurationValueCommand: Create or update configurations with history tracking
- DeactivateConfigurationCommand: Deactivate configurations with audit trail

Queries:
- GetConfigurationByKeyQuery: Retrieve configuration by Scope and Key
- GetAllConfigurationsQuery: List all configurations with filters and pagination
- GetConfigurationHistoryQuery: View complete audit history for any configuration

Features:
- All commands include FluentValidation validators
- History recording to SystemConfigurationHistory table
- Pagination support for list queries
- DTOs for clean data transfer
- Null-safe implementations

Updated:
- IApplicationDbContext: Added 11 new DbSets for network-club entities
- GlobalUsings: Added new entity namespaces

Build Status: ✅ Success (0 errors, 184 warnings in legacy code)
