security: harden dashboard (SSH keys, auth, uploads, CORS, non-root)
Remove SSH private keys from git, add SECRET_KEY validation, move WS
auth from query string to first message, add session limits/idle timeout,
PBKDF2 Fernet key, refresh token rotation, TOTP replay protection,
file upload size limit + filename sanitization, symlink safety check,
restrict CORS methods, IP-gate OpenClaw token, run container as non-root,
rate-limit refresh/passkey endpoints, sanitize Gitea path params.
