* fix(gateway): prevent auth bypass when behind unconfigured reverse proxy
When proxy headers (X-Forwarded-For, X-Real-IP) are present but
gateway.trustedProxies is not configured, the gateway now treats
connections as non-local. This prevents a scenario where all proxied
requests appear to come from localhost and receive automatic trust.
Previously, running behind nginx/Caddy without configuring trustedProxies
would cause isLocalClient=true for all external connections, potentially
bypassing authentication and auto-approving device pairing.
The gateway now logs a warning when this condition is detected, guiding
operators to configure trustedProxies for proper client IP detection.
Also adds documentation for reverse proxy security configuration.
* fix: harden reverse proxy auth (#1795) (thanks @orlyjamie)

The device identity check was rejecting connections before token
authentication could be attempted. This broke the control-ui (web UI)
which uses token-based authentication via URL parameter.
Changes:
- Skip device identity requirement when a token is provided
- Guard device token verification to only run when device is present
Fixes control-ui showing "device identity required" error when
connecting with a valid token.
