* feat(gateway): auto-approve trusted-proxy browser device pairing
Adds gateway.auth.trustedProxy.deviceAutoApprove so team gateways behind an
identity-aware proxy (Cloudflare Access, oauth2-proxy, Pomerium) can skip the
manual `openclaw devices approve` step for new Control UI/WebChat devices.
Auto-approval fires only for a new (unpaired) operator browser device on a
connection that already passed trusted-proxy auth with a resolved allowUsers
user. Scope upgrades on existing devices and node pairing stay manual. Granted
scopes are capped to the configured set intersected with the connection's
x-openclaw-scopes proxy cap, operator.admin is rejected at config validation,
and the pairing-store approval rechecks new-device status under the store lock
so a repair/upgrade or concurrent approval can never be silently widened. Each
auto-approval emits an audit log line with the proxy user and granted scopes,
and `openclaw security audit` warns when the mode is enabled.
