Systematically add platform_admin and platform_super_admin to all
controllers that were restricted to 'admin' only:
- audit-service: queryLogs, exportLogs
- inventory-service: decryptCredential
- auth-service: RoleController, PermissionController

Implement remaining backend controllers for all web admin menu pages:
- SettingsController: general, notification, theme, account, API keys
- RoleController: CRUD roles with permission assignment
- PermissionController: permission matrix for RBAC management
- MetricsController: server metrics overview and per-server data
