[BE-SEC-004] security: Implement CSRF protection for all state-changing endpoints

- Created applyCSRFProtection helper function to apply CSRF middleware
- Applied CSRF protection to all protected routes with POST/PUT/DELETE:
  * Users routes (PUT, POST, DELETE)
  * Tracks routes (POST, PUT, DELETE)
  * Playlists routes (POST, PUT, DELETE)
  * Chat routes (POST)
  * Auth protected routes (POST logout, 2FA)
  * Roles routes (GET only, no state-changing)
  * Marketplace routes (POST)
  * Webhooks routes (POST, DELETE)
  * Comments routes (POST, DELETE)
- CSRF token endpoint (/csrf-token) remains accessible without CSRF check
- Middleware validates X-CSRF-Token header for all state-changing requests
- Protection only applies when Redis is available

Phase: PHASE-4
Priority: P1
Progress: 6/267 (2.2%)
