"""
RMI Admin Backend Router
==========================
Complete admin panel API with RBAC, security, and management tools.

All endpoints require X-Admin-Session header (JWT session token).
Some endpoints also require specific permissions based on role.

Sections:
  1. Authentication (login, logout, session, 2FA)
  2. Dashboard (metrics, health, analytics)
  3. User Management (users, bans, roles, activity)
  4. Security (IP blocks, rate limits, audit logs, threats)
  5. System Management (config, services, health)
  6. Content Management (posts, announcements, SEO)
  7. Financial (x402 analytics, revenue, payments)
  8. API Keys (create, rotate, revoke, scopes)
  9. Token Deployer (darkroom integration)
  10. Backups & Maintenance
