Refactor: Implement Centralized Configuration Service with Dynamic Reloading

[Smartdevs17]

Context

Configuration is scattered across environment variables, JSON files, and database tables. Changing a config requires redeployment.

Current Limitation/Problem

No centralized configuration management. Feature flags, fee schedules, rate limits, and provider settings are hardcoded or in env vars. Configuration changes require code deploys.

Expected Outcome

A centralized configuration service with hierarchical overrides (default < environment < database < admin override), dynamic reloading without restart, and an admin UI.

Acceptance Criteria

• Configuration schema definition with types and validation
• Hierarchical resolution: defaults < env < database < runtime override
• Dynamic reload of changed configs on config change event
• Admin API for reading and updating configuration
• Audit log for all configuration changes
• Config change notifications to subscribed services
• Config export/import for environment migration
• Frontend admin UI for configuration management

Technical Scope

• backend/src/services/config/ - configuration service
• backend/src/services/config/config-store.ts - storage abstraction
• Redis pub/sub for config change notifications
• Prisma: AppConfiguration, ConfigAuditLog models
• Frontend: /admin/configuration - config management UI
• Migration: move existing env vars to centralized config
• Edge cases: invalid config values, partial updates, concurrent modifications
