fix: implement 22 security pentest remediation fixes

Server-side session management with SHA-256 hashed tokens and HttpOnly
cookies. Auth middleware gating all RPC/WS/proxy routes with method
allowlist. Login rate limiting (5/60s per IP). CORS restricted to
config origin. Docker registry allowlist. App ID and path validation.
P2P message sanitization (HTML + log injection). Onion address and
known-peer validation. Nginx security headers (CSP, X-Frame-Options,
etc.) and AIUI proxy auth. Systemd hardening (non-root, NoNewPrivileges,
ProtectSystem).
