Agent Zero 604a2b7648 Phase 2: Fix high-priority security and stability issues (H1-H7)
H1: Sanitize error endpoint context (strip tokens/passwords, limit depth/size)
H2: Rate limiter IP spoofing fix (trusted proxy CIDR check for X-Forwarded-For)
H3: CSRF middleware uses Redis singleton instead of per-request connection
H4: WebSocket origin verification added to both kommunikation and ai_ui_control
H5: Storage path traversal protection, get_url() returns relative URL not filesystem path
H6: Security headers middleware (HSTS, X-Content-Type-Options, X-Frame-Options, CSP, Referrer-Policy)
H7: Forward-repair migration 0045 for databases that ran original 0021/0027

Also: add trusted_proxy_cidrs to config, add verify_ws_origin to auth
