The dashboard's gateway status detection relied solely on local PID checks
(os.kill + /proc), which fails when the gateway runs in a separate container.
Changes:
- web_server.py: Add _probe_gateway_health() that queries the gateway's HTTP
/health/detailed endpoint when the local PID check fails. Activated by
setting the GATEWAY_HEALTH_URL env var (e.g. http://gateway:8642/health).
Falls back to standard PID check when the env var is not set.
- api_server.py: Add GET /health/detailed endpoint that returns full gateway
state (platforms, gateway_state, active_agents, pid, etc.) without auth.
The existing GET /health remains unchanged for backwards compatibility.
- StatusPage.tsx: Handle the case where gateway_pid is null but the gateway
is running remotely, displaying 'Running (remote)' instead of 'PID null'.
Environment variables:
- GATEWAY_HEALTH_URL: URL of the gateway health endpoint (e.g.
http://gateway-container:8642/health). Unset = local PID check only.
- GATEWAY_HEALTH_TIMEOUT: Probe timeout in seconds (default: 3).
